Bug ID: 498757 Summary: Debian Trixie KDE causes GPU clock spikes on Virtual Desktop switching Classification: Plasma Product: kwin Version: 6.2.5 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: performance Assignee: kwin-bugs-n...@kde.org Reporter: fabio900...@gmail.com Target Milestone: --- Created attachment 177425 --> https://bugs.kde.org/attachment.cgi?id=177425&action=edit Here, as you can see, the spikes are very predictable and common, happening every virtual desktop switch. *** SOFTWARE/OS VERSIONS Operating System: Debian GNU/Linux 12 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.8.0 Qt Version: 6.7.2 Kernel Version: 6.12.9-amd64 (64-bit) Graphics Platform: Wayland Processors: 12 × 11th Gen Intel® Core™ i5-11400F @ 2.60GHz Memory: 31.2 GiB of RAM Graphics Processor: AMD Radeon RX 6650 XT *** SUMMARY Debian Trixie (KDE Wayland) here. I installed the latest LACT .deb package and for tuning purposes, on my RX 6650xt, I kept an historical data graph. What I noticed is that changing virtual desktop causes a GPU clock spikes. I did alread notice KDE having ordinary stutters, especially now that I havea 165Hz monitor. STEPS TO REPRODUCE a. Change Virtual Desktop via shortcuts. b. Change Virtual Desktop via mouse. b. Disabling system animations, specifically Virtual Desktop switching animations, doesn't solve the issue OBSERVED RESULT The overall system performance, over intense GPU sessions, is very stable and performant, albeit whenever I switch to the Virtual Desktop overview using the mouse gesture, i.e., moving the cursor over the top-left corner in my case, there is a recurring clock spike which leads to stutter. I also forced the P-State to be only 2750 Mhz, yet, the stutters and clock spikes were still happening -- You are receiving this mail because: You are watching all bug changes.
