I don't think that’s the good idea even if possible to do with env variable. This should just work correctly, you either miss something in your system or hit some nasty bug of your distro/build or it’s general KDE bug
Do you mean PROTON_USE_WINED3D=1 ?
If so, you don’t have Vulkan compatible hardware (GPU from like before 2012) or missing drivers. With this flag you use OpenGL rendered instead, that is inferior in every way. If you try it on modern hardware with the right driver in place you’ll get much worse performance, if it even works. This flag shouldn’t be promoted generally.
If you run ancient GPU and want to always fallback to OpenGL, you can put the line
PROTON_USE_WINED3D=1
in /etc/environment and reboot. No need to set that in properties for every individual game.
Find jellyfin related file in /etc/apt/sources.list.d, edit it as root and try replacing „circle” with „bookworm”.
After that apt update and retry. If it doesn’t work you can also try replacing it with „noble” but the you might also need to replace debian -> ubuntu, but that’s just my guess
Install wine and yabridge follow setup instructions on how sync your plugins, which essentially takes specified locations with VST2/VST3 DLLs and creates .so equivalents (Linux dll format) under specified location that under the hood calls Wine, but makes it transparent. You add that location (with .so files) in your DAWs search paths and it should scan those plugins like if they were native.
Of course some compatibility issues are possible, but you should be able to run most stuff this way when it comes to plugins.
You don’t need to. Modem browsers will suspend unused tabs, cache them on drive and free up the memory, while quickly restoring as soon user activate them. On at least moderately fast systems this happens so quickly it’s hardly noticeable.
