Is anyone also having problems? I am all updated to 2009, all drivers updated. SFC reports no issues. Occasionally, when there's a crash my screen goes black for a few seconds.

    I can confirm that the issue is still present on my Surface Pro 7 as well. I used the pen at work this week and encountered the black screen issue again. Darn!

    Unfortunately, I just got another DWM/Heatcore.dll crash, so I was wrong, appears the bug is still with us.

    But I want to say it's decreased in frequency. Just one so far.

    So funny that you'd post this today. It occurred to me a few minutes ago that on Tuesday this week I did the cumulative Windows update and also saw there were some firmware updates that were also downloaded and installed that may have addressed the black screen issue. I tested my Surface Pro 7 a few minutes ago with the pen and didn't experience the issue. 

    I'll have to try to use my pen a bit more throughout this week and see if the issue continues to not show up.

    I'm optimistic the updates from this week might have fixed these issues. One of the updates was for Surface Service which was one of my problem events

    Yes sorry. I had relied earlier in the thread confirming I had issues with the black screen upon using the pen. The error log from Event Viewer shows:
