Surface Pen makes screen flash black

Hey, WHAT driver did you replace? That might help us as well...

Google intel graphics drivers, and install their automatic updater. In the list you will get 3 updates, just update the Graphics one with the "non OEM" version.

Hey, WHAT driver did you replace? That might help us as well...

Thank you Selimrecep and Erwin for your responses it helps, would be good if Microsoft were as helpful! I am not on Win 20H2 but sounds like updating to that won't make any difference. I am using a surface Pro 7. It's a good tip to switch on the ruler that workaround fixes it for me (in a clunky sort of way) :-)

Great it worked for selimrecep and Erwin, but it didn't for me, I updated (against the Tablet's (Microsoft's) advice) to Intel graphics driver 27.20.100.9168.  Is that the same one that fixed it for you two? I had previously updated driver/firmware on windows update to 17763_20.020.2886.0. My issue only happens with whiteboard and as others have pointed out, only when using solid not rainbow colours - was that the same for you?
I also have had screen brightness flitting whilst the auto-adjust brightness was set - so have had to disable that.

Actually I don't know Erwin but the issue was same for me, after upgrading drivers it was fixed. Can you use solid colours when ruler is open, though? I was able to do use them when ruler was open.

If helps:

Windows 10 20H2

19042.746 (I don't know what is this, I found this on Windows Update)

Intel Iris HD Graphics 630 with 27.20.100.9168 version (seems like same with you)

Gtx 1050 Ti with 461.40 version Driver

Selimrecep can you provide a link to the Intel iris hd driver you downloaded?

Hi! Sorry for late reply. Actually I've used "Intel Driver & Support Assistant" to update my graphics driver. By the way, I am using I5 8300H which has Intel Iris HD Graphics 630 (with version of 27.20.100.9168, as I updated. You can check your driver version from "Device Manager" if you want) if you ask. But I don't recommend manual install though (I mean there is an assistant that does for you). I downloaded Intel Assistant thing, it asked me if I want to overwrite an OEM graphic driver (which might cause issues, in my case, it didn't), I confirmed dialog and updated my display driver. It was fixed. Actually in my case it was something about OEM driver. When I was using OEM driver, the HP web site was clearly saying ".... (Windows 10 v1709)" which makes sense to have a broken driver because I upgraded my Windows to 20H2. After that, the whiteboard bug thing happened I guess. I am not using surface pen though neither tablet, just a regular PC (if it helps, just a entry level gaming pc). I know this forum for Surface tablets, but somehow same problems applys for a lot of people....

Such like, in Microsoft Whiteboard (in OneNote that happens too) when you have that bug, you can't use solid coloured pens , but you can use rainbow ones. In my case, I was able to use solid coloured pens when ruler was open (which is... weird. I saw this thing on uservoice website and tried it, it worked with ruler on).

As a result, I think it is a compatibility issue about OEM drivers and Windows. Still strange Microsoft didn't fully address this issue...

Edit: I also tried to install all Windows Updates, only updating iris driver helped me in this case. I also checked group policy thing, I already had that use (which has an username I don't remember right now), so it didn't help me either, I also tried to remove that user and add back, didn't help...

Surface tablets might have another issue. I don't know. But, really, I am using a PC and I might not expect the whiteboard application not work or neither OneNote pen drawer because, well, my screen is not a touchscreen :D I don't use this feature much, but this issue wasn't addressed for long time as I see, Microsoft should find a solution for this I guess, especially for surface pc users (which has touchscreen and a pen).
