I can confirm this on kwin_x11.
STEPS TO REPRODUCE:
1. Enable KWin FPS desktop effect
2. Install Infinity-Aurorae window decoration
3. Make the desktop effect for switching desktops (e.g. Slide) slow (between
1200 and 1500 ms should be enough)
4. Use a dark wallpaper (to make the FPS effect show up better)
5. Have any window open in one virtual desktop and keep the other empty.
6. Switch between desktops
OBSERVED RESULT
(My screen refresh rate is set to 60)
(Let's call virtual desktop a VD)
If I'm using Breeze:
In a VD with windows open, FPS is 60, and when you attempt to switch to an
empty VD, during the effect FPS lowers to a max of 47, and afterwards it goes
back to 60.
a.k.a. 60 > 47 > 60
In an empty VD, FPS is 60, and when you attempt to switch to a VD with open
windows, during the effect FPS lowers to a max of 47, and afterwards it goes
back to 60.
a.k.a. 60 > 47 > 60
Compare this with when I'm using Infinity-Aurorae:
In a VD with windows open, FPS is 47, and when you attempt to switch to an
empty VD, during the effect FPS stays mostly the same (47), and afterwards it
goes up to 60.
a.k.a. 47 > 47 > 60
In an empty VD, FPS is 60, and when you attempt to switch to a VD with open
windows, during the effect FPS lowers to a max of 44, and afterwards it goes up
to 47.
a.k.a. 60 > 44 > 47
EXPECTED RESULT
With a refresh rate of 60, you should have
60 > 47 > 60 no matter the theme used.
