Overall, the animations look good, but every time I use the overview effect, I experience laggy animations and FPS drops. I've updated to KDE 6, and even with the new overview design, the issue persists. STEPS TO REPRODUCE 1. Login 2. Trigger overview effect using screen edge or META+W shortcut 3. lower FPS than normal and feeling laggy OBSERVED RESULT FPS drops notably than normal usage of plasma EXPECTED RESULT Overview desktop effect 144/60 fps and no fps drop/"feeling laggy" SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) Kernel Version: 6.7.8-zen1-1-zen (64-bit) KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION using both 60hz and 144hz issue persist. in 60hz FPS drops to 38 and in 144hz FPS drops to 117. 2297134 1 hsaom 2024-03-08 12:04:24 +0000 Hardware AMD Ryzen 5 5600H 16 GB AMD Radeon RX 6600M Graphics 2297189 2 bug-janitor 2024-03-08 13:53:27 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/5390 2305801 3 xaver.hugl 2024-03-26 16:14:44 +0000 Git commit d59451adcf8f7a4d90659a60bfbe73230091b0e3 by Xaver Hugl.

Every next animation is smooth. I'm opening overview using touchpad gestures if that matters.

In my case, the screen freezes for a couple of seconds, and then moves at sluggish speed until the animation is completed.
