So it looks thesame (maybe a little less) but happens under different circumstances? I'm experiencing a similar issue and maybe got a temporary fix. All I know is that with my laptop (Lenovo Yoga C940 14IL) i've got thesame flickering as in that issue on Kubuntu 19.10, Kubuntu 20.04 and Fedora KDE 31. Those are all 5.3.x and 5.4.x kernels if I got my kernel numbers right. I've tried upgrading Kubuntu 20.04 to mainline kernel 5.6.0-050600 and that didn't work. Upgrading to 5.7-rc2 seems to work, but network card doesn't work out of the box.
I've tried this issue with OpenGL 2.0, 3.1 and XRender with various settings for vsync, that does have major effect to occurrence, and that's why I think that how often it occurs isn't that important. Could you try to install 5.6.0-050600 and 5.7-rc2 to confirm that the underlying issue is thesame and fixed in 5.7? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872760 Title: i915 - after return from suspend display is flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
