On updating to the 530 drivers I noted every once in a while my screens on my primary GPU (GTX 1660) will flash/flicker up top in like the topmost 1/3rd of the screen. There doesn’t seem to be any application or workload that triggers it, just happens randomly.
My Secondary GPU (GTX 1060) isn’t affected.
Rolling back to 525 the issue is no longer present. It has been a long time since I even logged in here and forgot the check the driver issue reporting post. As such I do not have the logs or outputs requested. If I notice a point release and try it I will try to nab logs and output then if it persists.
I had been using 530.41.03 (security fix) all morning and had no flicker. This made me think the memory issues that led to the security problems was also the cause of the flicker and the update fixed both. However I just noticed it happen. So while it’s much less frequent with the update it’s still there.
Attached Log is without the “startx – -logverbose 6.” X is set to run with -logverbose 6 when I restart my session.
Well good I’m not alone. I had searched for others having posted before me but my search terms didn’t find anything. Hopefully it will get fixed soon. While the .41 update is less obnoxious than the .40 was it’s still annoying.
So the issue is affecting GTX and RTX cards, high/low refresh panels, KDE and I don’t run a DE (CTWM). I also had a kernel update so it wasn’t the original kernel and looks to be affecting you on an LTS kernel as well. I wonder if it’s an issue with compositors. Perhaps I’ll quash mine for a bit.
***Purely anecdotal ATM but since I killed my compositor I’ve not seen the flickering. If this continues then it would suggest the bug is tripping up my compositor (picom). Either way hopefully it’s fixed since rolling back to 25 everything is good but now 25 is a security liability.
