[Bug 1897853] Re: [regression] gnome-shell stutters noticeably with kernel 5.8.0-19, but not 5.8.0-18
FWIW today 3.38 was released to Arch stable repo and I tested it using kernel 5.8.10 and 5.8.13. For the same governor, energy performance and gpu min freq settings, stuttering in the overview has increased a bit (HiDPI screen & 620, I think you already know that at this point). Anyway I've seen many fluctuations since 3.34 when using different kernels so it doesn't surprise me, seems like subtle timing issues that probably won't be 100% fixed by freq scaling alone but also by the additional buffering provided by !1441. Will take a look at Ubuntu beta this weekend and let you know about my experience there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897853 Title: [regression] gnome-shell stutters noticeably with kernel 5.8.0-19, but not 5.8.0-18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1897853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not sure what are you using as energy_performance_preference but I've seen important improvements in scaling speed when using balance_performance instead of balance_power, without the need to set the governor to full performance. I'm in Arch at this moment and can't remember if Ubuntu defaults to balance_performance or balance_power, though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897853 Title: [regression] gnome-shell stutters noticeably with kernel 5.8.0-19, but not 5.8.0-18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1897853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
