[Wayland / Multi-Hz] Animation FPS caps: Applet popups locked at 60Hz and Overview triggers system-wide 60fps lock (Plasma 6.7.3)

Hi everyone,

I’m running into a couple of annoying animation issues on Wayland with a mixed refresh rate setup, and things got a bit worse after updating to 6.7.3. I wanted to share my findings here to see if anyone else is seeing this or knows what might be going on.

System info:

  • OS: Manjaro Linux (6.18.40-2-MANJARO)
  • KDE Plasma: 6.7.3
  • KDE Frameworks: 6.28.0
  • Qt Version: 6.11.1
  • Graphics Platform: Wayland
  • GPU: NVIDIA GeForce GTX 1070
  • Monitors: Dual-monitor setup. Primary: 165 Hz, Secondary: 60 Hz
  • Switched branch to ‘unstable’ to get the newest packages

Issue 1:

Applet Popups Capped at 60 FPS (Long-standing)
Applet expansion (Application Launcher/Kickoff, Volume Control, System Tray popups/elements, etc.) on Wayland are hard-capped at 60 FPS on the primary 165 Hz display.

  • On X11 (single monitor setup), these animations correctly scale to 165 Hz.
  • On Wayland, regardless of whether 1 or 2 monitors are active, applet popups always run at 60 FPS.

Issue 2 [REGRESSION]:

Opening Overview breaks all window animations

This is a new regression that started happening after updating from 6.6.6 to 6.7.3.

  1. Right after logging in, normal window animations (minimize, maximize, open/close) are super smooth at 165 FPS.
  2. The moment I open the Overview effect (Meta + W or Meta + G), all window animations across the system immediately get capped at 60 FPS.
  3. Closing Overview doesn’t fix it. All window animations stay stuck at 60 FPS until I log out and log back in OR it randomly fixes itself after some time.
    This never happened on Plasma 6.6.6 where everything worked as expected.

What I found out by testing:
Back in Plasma 6.6.5, a user on my bug report pointed out Kwin commit [ Drive our QAnimationDriver fully by presentation timestamps (40f41b49) · Commits · Plasma / KWin · GitLab ] as the cause for Overview running at 60 FPS. (another regression btw)
Building KWin without this commit fixed the Overview animation running at 60 FPS on dual-monitor setups.

I tested Plasma 6.7.3 with and without this commit again:

  • Stock KWin 6.7.3: Overview runs at 60 FPS, and using it locks all other window animations to 60 FPS afterward
  • With commit reverted on 6.7.3: The Overview effect itself becomes smooth at 165 FPS again! However, once I exit Overview, all standard window animations (minimize/maximize) are still stuck at 60 FPS

Additional logs:
When closing Overview, I also noticed these warnings in KSystemLog for kwin_wayland:
27.07.2026 19:24 kwin_wayland Could not delete texture because no context is current
27.07.2026 19:24 kwin_wayland Could not delete render time query because no context is current

I don’t know if these are useful but I am sending them just in case.

Is anyone else on NVIDIA/Wayland experiencing this animation lock after triggering Overview? Has anyone else with high refresh rate screens noticed this? Any ideas?
