Issue description:
After updating from the 20240418 snapshot, my system got performance issues. For example, when cycling through tabs in firefox by holding ctrl+tab, it doesn't go through all tabs smoothly. There wasn't such a problem in the 20240418 snapshot.

Other performance issue occurs when trying to play videos in a virtual terminal with mpv using the tct output driver (it uses colored Unicode block characters) and sw-fast profile while Plasma is running or a user has logged out of it. mpv drops frames, which doesn't happen on the old snapshot. Bash completion with Plasma running has a delay with completing mpv options, that also didn't happen on the old snapshot. Without Plasma launched the Bash completion seems faster. I've also tested it with IceWM to check if it is directly related to Plasma and here are the combinations and results:
1. Boot, sddm loads, I don’t start any desktop session and switch to virtual console. No frame drops here.
2. Boot, sddm loads, start IceWM desktop session, switch to virtual console. No frame drops here.
3. Boot, sddm loads, start IceWM desktop session and log out of it, switch to virtual console. No frame drops here.
4. Boot, sddm loads, start X11 or Wayland Plasma desktop session, switch to virtual console. Frame drops happen.
5. Boot, sddm loads, start Wayland or X11 Plasma desktop session and log out of it, switch to virtual console. Frame drops happen the same as with Plasma running.

It could be an issue with mpv itself, but running it the same way in Konsole (with the tct output driver) doesn't show such performance issues. Bash completion is still slow in Konsole, though.

Other issue is a weather forecast website windy.com that has an animated wind map. It worked well on the old snapshot but now it performs very poorly. Tested on firefox.

3D graphics performance in glmark2 seems to be normal and similar to the old snapshot.

Please try booting the older kernel first and check whether performance is back to the previous level.

If not, please try downgrading Mesa, or rollback to the old snapshot and try upgrading mesa.

Many other cases (see forum) where caused by mixed Mesa packages from packman/openSUSE. So make sure that all packages come from either openSUSE or packman. 

E.g. switch all packages to packman via
"sudo zypper dist-upgrade --from packman --allow-vendor-change"

You need to replace "--from packman" with the proper repo name on your system.

I ran the command and it updated some vlc stuff and radeonsi changed vendor to packman. The performance is unfortunately the same.

Unfortunately, I didn't do anything to protect the snapshot from getting automatically cleaned up and it's not on my system anymore. The oldest snapshot I have is 20240516 and it is affected by the issue. But I remember testing updating only Mesa on the old snapshot. It has caused some visual glitches back then, but if I recall correctly it didn't cause performance issues (although I only tested mpv as it was the most obvious one).

I haven't used the laptop in a while, but on snapshot 20240714 I don't get frame drops in mpv with the tct driver. I see a new Mesa version on my system (24.1.3-1699.387.pm.1) so that could be one of the reasons. I've also noticed some improvement in desktop performance on my nvidia desktop, so there could have been some other fixes in the meantime. I think I can close this bug as mpv was the main program where the issue appeared.
