[Bug 1923632] Re: Screen flickering
For lswh read lshw - sorry! This problem is pretty bad on my system - it becomes unusable after a while. I will have to avoid any kernel upgrades. Given that the problem seems to happen after a while, and then gets worse and worse, I wonder whether it is some sort of corruption issue that gets worse as the corruption grows. It doesn't seem to be a fundamental graphics issue that happens every time a certain set of actions takes place. That probably means it will be difficult to track down, and may vary a lot between systems. I'm willing to try and help analyse the issue, but I have no idea what data I could provide to help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1923632 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1923632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1923632] Re: Screen flickering
I have the same problem on that kernel (ubuntu 20.10), and on the update to 5.8.0-50.55. I have gone back to 5.8.0-48.54 and it has stabilised. I get all sorts of different effects. Blocks of text being partially blank, whole menu boxes being blank, and so on. This usually happened after the system has been on for a few hours, so I initially suspected hardware, but reverting to 5.8.0-48 fixed it. The worst effected are browsers (Firefox, Chrome and Brave) possibly only when not full screen, but parts of the application icon toolbar and others parts flicker on and off as well. I tried wayland, but it was no better, so an x.org update may not help (I can't see one available at present) I'm using "Intel® HD Graphics 4600 (HSW GT2) graphics", on "Intel® Core™ i7-4770T CPU @ 2.50GHz × 8". No special drivers.

Is the problem tearing or flickering? In which apps? Only when full screen?

Hello, I was affected by the same bug as you following the Linux 5.8.0-49-generic kernel update (everything is ok with the 5.8.0-48-generic kernel) However, the problem has been solved with the X.org update which has been available for a few hours. Can you look for new updates available and test after updating the X.org server and restarting the PC? My PC : - Dell Inc.
