Been having similar issues here, on Zorin OS. DS4 controller(s) sometimes disconnect, sometimes one of them gets noticeable input delay. Then, after some time or some update, the controllers stopped connecting automatically to the dongle I am using, even though they were already paired to it. Actually, I think they stop connecting automatically only after I reboot the computer, so that means it's an OS / software issue. It's a cheap bluetooth dongle, so at first I thought that chinesium was to blame, but seeing as others have these problems...
I have nvidia, and I can't use any other proton version that is higher than ge-7.50. It's probably a software issue, but I can still play many games, both new and old. I have gtx 1060 6GB. Using Zorin OS.
Oh, sometimes, the driver update gets stuck, and I have to use a command (dpkg --configure -a) to resume it after a system reboot.
Pretty sure that the ukrainians are the real refugees here, and not ruzzians.
