haruna sidebar choppy animations

SUMMARY
I'm testing on KDE Linux on KDE Plasma 6.6 dev, and I'm using wayland and a nvidia 4060 card, and I've noticed that when I'm playing a video in Haruna and I open the sidebar, the opening animation seems capped at 30hz and looks choppy and laggy, but if I pause the video then the animation of the sidebar seems to follow the refresh rate of my screen (144hz) and looks smooth


STEPS TO REPRODUCE
1. Play a video in Haruna
2. Open the sidebar
3. 

OBSERVED RESULT
The sidebar animation is choppy and laggy and seems capped at 30hz

EXPECTED RESULT
The sidebar animation is smooth and follows the refresh rate of the screen

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Linux
KDE Plasma Version: 6.5.80

Qt Version: 6.10.1

That rendering is all internal to the app, KWin isn't involved in it.

If you use a high refresh rate video, is the animation smooth then?

I've recorded a 144hz video but no, the haruna sidebar opening animation is still choppy and laggy even with that 144hz video playing.

Test with the following custom commands, run at startup
1. "set override-display-fps 75", replace 75 with your monitor's refresh rate
2. "set video-sync display-resample"
