its an AMD RX 7900 XTX
and yes x11 works without problems in games but all in obs is builded around wayland.
and its a bug.? any possible idea to fix it? maybe install an old october release?
Well, if you think it is Plasma 6.2 you can wait about 2 hours until the CI finished a rebuild of 6.1.5 release, get the packages and create a local repo on your end: Releases · manjaro/plasma-6.1 · GitHub
Right, sorry. Well you can try to see if it is a kernel issue then. Some reported issues with 6.11+ and AMD cards. Releases · manjaro-kernels/linux610 · GitHub. You may want to put the linux-meta packages on ignore list to not get linux610 kernel removed automatically.
small info what i testet:
downgraded the kernel to 6.10 - not worked also tearing
downgraded mesa to 24.2.4 - also tearing
switched to 6.12 kernel - same issue
Well, you could download the PKGBUILD of kwin 6.1.5, add the line epoch=1 and build it against the Plasma 6.2.4 packages you have now to see if that changes something.
