Can you test the same scenario after putting KWIN_DRM_NO_DIRECT_SCANOUT=1 into /etc/environment and rebooting? Do you still see stutter then? Created attachment 170194 [details] attachment-3246432-0.html Yes, I will do that when I get the chance tomorrow and follow up with you.

Do you still see stutter then? -- You are receiving this mail because: You reported the bug. Just following up, I can confirm that after setting the environment variable KWIN_DRM_NO_DIRECT_SCANOUT=1 and rebooting, there is no stutter present and everything is perfectly smooth in the same gaming scenario when receiving desktop notifications. This likely points to a bug in the direct scanout implementation. okay, then direct scanout is definitely getting interrupted, when it shouldn't be. Do you have any effects that would be acting on notifications? Created attachment 170350 [details] attachment-4014901-0.html Reviewing the Desktop Effects KCM, the only thing that stands out is the effect called "Fading Popups" as they seem to smoothly fade in and out when they show and disappear. I didn't make any changes to this module and use the default effect settings as packaged by Arch/EndeavourOS. Thanks for looking into this minor, but still important issue. ________________________________ From: Zamundaaa <bugzilla_noreply@kde.org> Sent: June 9, 2024 12:42 PM To: robert.bielski@outlook.com <robert.bielski@outlook.com> Subject: [kwin] [Bug 487780] Fullscreen game stutter when Plasma receives notifications. https://bugs.kde.org/show_bug.cgi?id=487780 Zamundaaa <xaver.hugl@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Resolution|WAITINGFORINFO |--- Status|NEEDSINFO |CONFIRMED --- Comment #4 from Zamundaaa <xaver.hugl@gmail.com> --- okay, then direct scanout is definitely getting interrupted, when it shouldn't be.
