Steps of reproduction
run picom (picom repo or picom-git), run video fullscreen. i use youtube for example, enabling stats for nerds. see frame drops steadily increasing.
Meanwhile, when using the "picom-ibhagwan-git" repo, launching picom with the same flags and with the same config file, no noticeable frame drop is noticed.

Other details
I'm getting a very similar issue, however this issue is affecting everything, not just fullscreen video, and it has only started after the recent update to version 10. If I downgrade to version 9.1-3 it works perfectly.

It may have something to do with the now old default config I'm using, I'll see what happens with a new config, but I doubt it will change anything.
Update: after trying a new config, it's still stuttering droping frames, I'm going to stick with the old version for now.
@TotallyARobot did you use --experimental-backends before? if so, does --legacy-backends change anything?
@yshui That did actually fix it even though I wasn't using experimental-backends before, is there something I should change to get the current backends working? Or are the new backends just causing problems in general?
yeah looks like the newer backends are causing the problem. people have been testing it more >1 year, but i did expect to see more problems surfacing now it's enabled by default
it's hard to grasp exactly what the symptom is, are you able to maybe record a video ?
It shows up best when using something with smooth animations like cava (which is exactly what I used he) to show the differences. You will also see some problems with the fade in and fade out effects used by picom.

updated post, some notes were hidden by some "hidden" tags. youtube's simple frame drop counter would be a simple method to see frame drops. run video on fullscreen, enable stats for nerds
also, running picom with "--legacy-backend" are smoother than not having it but this disables blur methods
Is there any real way to disable picom while on fullscreen mode with a specific setting ??
