I was able to get hotkeys working via the websocket feature and KDE Plasma's Shortcuts system, bridged by obs-cli.
However, I was unable to get the input overlay plugin to do any more than display a static image, because it simply has no Wayland support at this time.
I might've been willing to put up with this loss and wait for the necessary backend rewrite but I've run into other issues and gripes with Bazzite that have pushed me back into the search for a suitable distro. I'm going to see if I can get one that still supports X11 but also doesn't cause OBS to drop a third of its frames whenever a game is GPU-intensive. Wish me luck.
i think its to do with Linux itself not the plugins or obs, due to hotkeys and plugin issues ive came across i fix half of 75% of my issues but with the overlay stuff it dosnt even work with NohBoard overlay app its a shame
the big problem is having linux with Wayland ive seen so many topics online about this and their been a fix but since the current updates still dosnt work now again, also seen topics that talk about the OBS team needs to update the Linux version to get hotkeys and overlays to work correctly too
Ive also run Bazzite and i dont have any issues of dropping fps in games or obs too, ill share a screenshot of stats on obs after doing a stream if ya like
