Pen tablet makes black screen when i'm using program from microsoft

Hi, everyone. After over a year struggling with this issue and, because of that, being unable to update my Windows to the 2004 or 20h1/20h2 version, I have finally figured out how to fix it.  It solved the problem 100%. Now I can draw on Whiteboard and all Office programs without my screen going black.
How to solve it:
Open any Microsoft Office program.

1. Click on the File tab in the upper left.
2. Select Options from the left navigation menu.
3. In the popup window, select Advanced from the left navigation menu.
4. Scroll down to the Display section and check the box to Disable hardware graphics acceleration.
5. Click OK.
6. Close all Office applications.
7. Restart your computer.

Also, update ALL your drivers.  It should work.

Please, let me know if this worked for you.

More attempts:

• Disabling hardware acceleration does not solve the problem (https://itssc.rpi.edu/hc/en-us/articles/360004737612-Solution-to-strange-display-or-black-screen-when-using-Office-programs)
• Changing screen resolution, screen refresh rate, etc. does not solve the problem

More tests on different software:

• The problem does occur in Microsoft Whiteboard
• Interestingly, the problem does NOT occur in Microsoft Teams when using the whiteboard in a meeting.

I have the same issue since 2 to 4 weeks ago. Using the pen in office applications (in Word, or in OneNote, or in PowerPoint...) 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, it stays black forever and I am forced to force-restart the computer.

It happens with ANY input device. It happens if I use my mouse, if I use my wacom tablet, if I use my XP-Pen.... it happens with all of them.

Being a university teacher, this is a big issue for me as I need to teach online and need to start recording videos for offline teaching.

VERSIONS:

Win 10 Home Edition

[Windows Update says I am up to date as of 16 December 2020]

Microsoft Office 365 ProPlus. 

[Word version is "Word for Office 365 MSO (16.0.12527.21296) 64-bit]

Peevious solutions in this thread didn't work.

I tried the solution by JoeCh1 on 1st August, to change "policy permissons" and it did not work (the policies were already set correctly. Also, in Win 10 home edition I had to find out how to enable the gpedit.msc first).

I checked what changes had occured on my computer recently.

My Microsoft Office 365 ProPlus was updated to version 16.0.12527.21330 on 12 Nov 2020. This is very shortly before I started to notice this problem, so I am currently inclined to think this version of Office could be the problem, maybe. 

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.

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.

I have the same issue on my touchscreen Dell XPS 9370.

The blinking or flashing occurs in OneNote, Whiteboard and even in PDF-XChange.  Strangely, it does not occur when selecting an eraser or lasso tool.

I have updated all Dell drivers on the laptop. This has not solved the problem.

I am currently running Windows 10 Enterprise v1909

The blinking/flashing occurs when I touch the screen with a stylus OR when I draw with the mouse.

I am very eager to get it fixed and would be grateful for Microsoft to acknowledge the issue and resolve it.
