At least it appears that we have our first actual reply from a dev, on the discord: "I thought we had fixed that in 1.4, but apparently not".
So the devs were indeed aware of the bug, they probably just threw it at the bottom of the priority list because it's linux (and it doesn't affect the holy steamdeck, I guess).
