I had a similar issue with Overwatch, adding LD_PRELOAD="" to the launch arguments fixed it. It seems like the issue I had is caused by a change in steam overlay for the new game recording feature, which happens even if the overlay and recording are disabled.

Git Repo, it works on Windows too, just in case you've activated it and the bottom corner of your screen feels lonely. You can also set the text to whatever you want
playerctl can list and control (most) media players individually, and would be suitable for writing a script with. In terms of rebinding keys you might be able to set them to run shell commands using global shortcuts in KDE system settings, although I’m not at my computer right now to test it.
Is one of your monitors HDR? I've been getting similar issues (EndevourOS) ever since upgrading to 555, where both of my monitors are black/no signal when logging into Wayland. Unplugging my primary monitor fixes the secondary monitor, and it seems like HDR is the problem in my case - https://bugs.kde.org/show_bug.cgi?id=488941
After deleting ~/.config/kwinoutputconfig.json, I could login. I did some tests and the issue happens when HDR is enabled. In the config file that put "highDynamicRange" and "wideColorGamut" to "true". Just changing "highDynamicRange" to "false" doesn't work, but if I put both to "false", I can login again.
Simply deleting kwinoutputconfig didn't fix the problem for me but I haven't tried setting it as read-only yet (Probably a good idea to back it up first). My X11 is working normally so I'll stick with that until this bug is resolved.
I struggled with this for a while, especially since my stream deck is a newer model with knobs and a touchscreen (streamdeck+) so most of the software I tried doesn't fully support it. Here is some of the software I have tried:
If you’ve tried any of these and it wasn’t working, it could be an issue with udev rules, if these aren’t configured the software cannot interact with the device.
Fontsource has a lot of the same fonts as google fonts (and a few extras like Iosevka). Keep in mind that they do not offer a CDN which means that to use the font in your project you must host it yourself.
