Just have to update Snip & Sketch on Microsoft Store, it worked for me! :)

We contacted Microsoft and apparently there was a setting on windows level that needed to be changed.
The policy "Increase scheduling priority" user right should have the following members assigned: "Administrators" group and "Window Manager\Window Manager Group".

I folks,
I was struggling with a very similar sounding issue with the Windows Snip & Sketch tool, and after trying a series of fixes from this thread and elsewhere, I found my solution that may help others to try out.
Full issue description: On pulling up the Snip & Sketch tool (using the default shortcut of Win+Shift+S), I found that on trying to mark up any image, I would in a best case scenario trace out a line with my mouse, but only see the mark appear after lifting my mouse button. Intended/expected behavior is to see the "ink" appear behind my mouse cursor as I am click+dragging. In a more typical worst case scenario, one or all screens would in the middle of making an inked mark briefly tear/glitch+flash black (as though they were temporarily disconnected by way of pulling the display cable from the back of the monitor), and the screens would not turn on until several seconds after the mouse button was released. This made sketching on screen snips tedious/sloppy as best, and impractical at worst.
The fix: Right click the desktop, Display Settings. Scroll down to 'Graphics Settings' (following 'Advanced Settings'). Choose 'Microsoft Store app' in the dropdown box, then 'Snip &" Sketch' in the following dropdown box. Add. Click on Snip & Sketch as it appears below in teh same view, and then click 'Options'. Select 'High Performance' instead of 'Let Windows decide'. In my case, subtext for 'High Performance' is "GPU: NVIDIA Quadro T2000". Subtext for "Power Saving" is "GPU: Intel(R) UHD Graphics 630". Save.
I found then on trying Snip & Sketch, that I got one instance of stuttering inking, then suddenly everything is working smooth and as anticipated! Yay!
Something else I did which may have contributed was opening the Windows Store, searching for Snip & Sketch, then updating. That alone did not fix the issue however and I had to perform the prior graphics settings tweak to make everything work.
Pertinent seeming details specific to my setup:
- Laptop is a Lenovo Thinkpad P53
- This laptop features *both* integrated (Intel UHD 630) and dedicated (nVidia Quadro T2000) graphics. You can verify whether you have 2+ active display adapters by looking at Device Manager > Display adapters.
- Thunderbolt 3 (USB-C) dock
- Two external monitors
- Windows OS build 19041.804 -

I fixed this issue with leaving my Intel OEM drivers and upgrading to latest Intel drivers, this issue happend after I upgrade Windows, seems like drivers weren't compatible?
I was able to use solid colours when ruler was open, but if not, screen was flickering, I was able to use rainbow colours without any issues. Also, this was happening in onenote solid coloured pens. But wasn't happening in Microsoft Paint.
I hope it helps...

Hi, I am experiencing the same issue here and this is my strange encounter:
I am using a Lenovo ThinkPad X1 Carbon laptop, together with a Wacom Cintiq tablet, and a Lenovo external monitor at home or a Dell external monitor at work. The Lenovo monitor has a USB C hub which is connected directly to the laptop, while the Dell monitor is connected via an external Dell USB C docking station.
At home, the Lenovo monitor is assigned as screen 2 and the Cintiq is assigned as screen 3 by default. I always duplicate desktop on both screen 2 and screen 3 so they show the same extended screen. Whenever I write on Cintiq using OneNote for Windows 10 or Whiteboard, the screen 2 (Lenovo monitor) would flicker with every pen stroke touching the screen, but screen 3 (Cintiq) appears perfectly stable without any flickering.
However at work, the Dell monitor is assigned screen 3 while Cintiq is assigned screen 2 by default. Both screens are set to duplicate the same extended screen just like settings at home. However, it is the screen 2 (Cintiq) that flickers with every pen stroke this time, while screen 3 (Dell monitor) remains perfectly stable.
This is rather frustrating, does the pen stroke triggering flickering issue only affect screen 2? I couldn't find any option in Windows that could swap the numeric order of the screen assigned.
What is even stranger is what happened this morning at work after I unplugged the USB C cable connected to the docking station (which output to Dell monitor) from the Lenovo laptop. It took a while for the computer to adjust to the new setting with only Cintiq connected. The screen on Cintiq remains flickering with every pen stroke, but when I reconnected the USB C hub again, the flickering on Cintiq suddenly disappeared and writing became perfectly smooth even though both screen 2 and 3 were running (no flicker on Dell monitor too). I am not sure if this will remain stable, or replicable the next time I connect the devices in this configuration again.
Hope this would offer a clue as what is causing the problem and how to avoid it.
Also, indeed when one turns on the ruler on Whiteboard, the flickering issue disappears. But turning on ruler on OneNote does not help at all.
This is rather frustrating, it looks like a persistent problem with Windows or drivers that have affected so many users for a couple of years. I find it unbelievable that Microsoft is unaware of this problem.

The problem occurs every time in: Word, PowerPoint, Excel and Whiteboard, Snip & sketch
Does not occur in : OneNote, Whiteboard for Teams.
The non solid pens both work in the whiteboard appAgain tried reinstalling, updating the app, graphics drivers and scaling/ hardware acceleration on the device.
My verdict to our rollout is to hold off until we see more replicable stability, or a backlog item we can track. -

Still not working...
Also strange that rainbow colors seem to work fine w/o the issue... -

I fixed it with Windows 10 and Huion Kamvas Pro 16.
When I was using some drawing apps, I changed the scale of tablet display to match the one I had on my computer (resolution was still the same!) from 150% to 100%. It resized all my apps to the same as on computer (original 150% made everything look weird, apps were bigger than they should). Then the issues began.
I did so many things, and nothing ever helped. But I just changed the scale back to 150% and it fixed everything.
Just go the the Screen tab, and select the scale option (for the tablet!) proposed by system, and shpuld be okay. Hope it helps.

Happens to me too since 3 or 4 weeks ago. I wouldn't call it a flicker, but screen turning black for a second or two for every stroke of the pen. I noticed that Windows 10 version 2004 was installed just before this started happening. Office 365 version 16.0.12527.21330 was also installed before this started to happen.
Here some info:
---- What happens:
Inking makes the screen go black as soon as I finish drawing any line, stays black for 1 sec, then it comes back. You draw another line, it goes black for another second, then comes back. Eventually, if I continue, it stays black forever and I am forced to force-restart the computer.
---- Where does it happen:
- The problem happens in all Office applications that I tried which have a "Draw" tab for inking: Word, PowerPoint, OneNote, Excel.
- It also happens in the Snip & Sketch software.
- It also happens in the Microsoft Whiteboard software
- Interestingly, does not happen in the whiteboards of MS Teams.
---- When does it happen:
I have investigated more how to replicate the problem. I can replicate it every single time in MS Excel, or Word by simply inking for a few seconds. On a new file, it starts working fine, but after I ink for a while (less than half a minute) then the black screen starts happening whenever I ink. I also noticed that it happens not only while inking, but whenever an inked line is "redrawn" in the screen. For example, sometimes when inking (e.g. in Word) the inked line will get "stuck" such that, when you scroll the page up and down, the inked line moves together with the scrolling (instead of remaining fixed in the page). When this happens, the screen turns black too when scrolling, even if not drawing. So, this means it is not the input itself, but the display of the line on the screen, what causes the problem.
---- Things I tried (without success):
- System restarts
- Use the "Repair" tool for MS Office. This updated my Office from version 16.0.12527.21330 to version 16.0.12527.21416, and restarted
- Reinstalled all graphics drivers and make sure I had last version, and restarted
- Restarted and launched Word in "safe" mode (with no plugins). Problem persisted.- Tried JoeCh1 's solution in the yellow box of https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/increase-scheduling-priority. But the settings suggested were already the settings I had, i.e. Window Manager\Window Manager Group was already in the Increase scheduling priority.

It briefly turns off the screen every time the pen first touches the surface. Not just the whiteboard, but the entire screen.
