Steps to Reproduce:

Reproduction case: https://github.com/microsoft/vscode/issues/146993#issuecomment-1131470956

I have no idea how to reproduce, I was clicking around in the file explorer when my mouse started flickering, including an icon on the side. it completely locked up and I had to terminate the process. When terminating it didn’t respond to the kill signal, so I had to force it to close.

It seems there is a back-and-forth race condition for setting the pointer style somewhere.

Here is a GIF demonstrating the behaviour observed:

Note that the speed of the flickering was much faster, and it is due to my recording software that you cannot see it flicker fast regularly. I am in fact trying to click on different parts of the application, but as you can see no click is getting through.

This bug makes vscode unusable on Linux, I have to killall -9 code every hour or so. Is there a status on this?

Thought I’d give an update on how to reproduce this bug. Turns out you don’t even need to click anywhere. Just do the following:

• make sure the sidebar is extended
• hover over an icon of the sidebar
• start moving slowly to the tip of the hover hint
• observe

vscode-flick.mp4 Things to note in my case:

• I could not reproduce it on zoom level 0 or below. Zoom levels 1 and 2 reproduce this bug. Try to increase the zoom level to see if it happens.
• From this first point, weirdly enough, staying on zoom level 0 seems to remove this issue, but then it’s annoying not being able to use other zoom levels without taking that risk of freezing.
• Disabling hardware acceleration didn’t change anything.
• I built (yarn) and ran (./scripts/code.sh) VSCode from source and couldn’t reproduce the bug. The pointer does flick back and forth, but only when it stays still; as soon as I move it a few pixels more it stops flicking. Also, the pointer flicking doesn’t block any shortcuts unlike in this demo.

After triggering the blinking taskbar right click vscode and then mouse mouse move to the right click option to move and keep the right click does not release about a few seconds will lift the blinking
