KDE Plasma Wayland - Explicit sync driver bug

There seems to be a driver bug in 555 where when kwin has explicit sync if the panel is set to dodge windows or auto hide and is hidden it freezes the entire desktop.
I have filed a report to kde which zamundaaa confirmed that this is an nvidia driver issue.

Hi @kodatarule
Thaks for reporting issue to us, I have filed a bug 4684578 internally for tracking purpose.
Could you please share nvidia bug report from repro state.

Here is the bug report:

On a side note, explicit sync in kwin also creates slight performance drops when opening apps(unrelated to the GSP Firmware bug).

I have the same problem too, i also reported it to KDE: https://bugs.kde.org/show_bug.cgi?id=488042
They told me they were going to fix it in the next driver so it’s just matter of waiting i guess…

Have you also noticed the decrease in performance when opening tray widgets? I’m using the stock panel BTW

That is separate issue and I think from what I read is related to the dynamic triple buffering they implemented, I saw they implemented a fix but it will be for the final 6.1 release not in beta. I have reverted to 6.0.5 for the time being until 6.1 gets more polish.

Well, that’s expected. I always thought it was something to do with triple buffering. Gotta wait for the release of Plasma 6.1 in June 18th then…
