Also want to add that all drivers are updated and this happens with both iGPU and dedicated Nvidia GPU
and wanted to mention I have both Stable and Preview versions installed

Is this only in pwsh? What if run it with -noprofile or temporary reset the prompt function function prompt { "PS $pwd> " }

This just looks like a bug with acrylic itself. Can you file feedback via the Feedback Hub? I don't know what the area path for that might be... maybe Composition? Effects? Not sure if those are real paths.

I suspect this might get better with #13935. The "flickering" you see looks like the titlebar showing through, even though it shouldn't be. I bet when we hide the titlebar in that PR, this will go away

@237dmitry No it's not just pwsh I tested it with other ones too and I did a profile reset also, I repaired the app but didn't make any difference I even tested different rendering options with the preview version

@zadjii-msft Oh sure here just made the feedback https://aka.ms/AAiq4zx, and also is there any ETA on when that PR will be on the preview version?

This issue seems quite unusual. I don't think we've seen anything like this before (with something like that green flickering), right? I hope your main memory / RAM isn't defective...

oh sorry I should have mentioned that green color is just my theme color I keep changing it to different ones time to time

also relevant:

• HDR "SDR Brightness" With Multiple Monitors Can Cause Acrylic Flicker #13200
  • this was promoted to MSFT:39958690, which is fixed, but unfortunately doesn't have a link to the commit, so I can't be sure which build that's in. Something >22621, that's for sure.

@zadjii-msft should I change my feedback from Category Apps > Windows Terminal to something else?

[zadjii-msft]

Hey just looping back on this, lost it over the holidays.

"Category Apps > Windows Terminal" probably won't get this to the right area path. That would go to us, but our feedback provider isn't gonna capture the graphics traces that {someone} needs. There's probably a more accurate one for a "composition" or "acrylic" area. Alas, Feedback Hub is turbofucked on my machine so I can't look it up myself 😕

It's also possible that this was something that was already fixed by the composition team. Did this happen to go away on its own/?

[poqdavid]

@zadjii-msft Well I just checked both Windows Terminal Preview Version: 1.17.1023 and Windows Terminal Version: 1.16.10262.0 they still have the same exact problem unfortunately

also what category I should change it to?
