I’m technically a little over a year. Didn’t boot Windows once and eventually wiped the drive it was on maybe 4 months in.

I have a persistent issue with my PC not waking up from Sleep (maybe 70% of times it goes to sleep, it requires a hardware power off and a second restart after booting or else the network and mouse don’t work), and despite dozens of searches, carefully reading systemd journals, and one two-week period where I thought a setting change had fixed it, it’s still here, and I usually just shut my PC down instead of gambling and wasting time.

Proton has mostly been excellent, aside from a few Battle.net updates that caused extremely strange issues which ultimately required a bleeding edge Proton build to fix.

Oh and there have been a couple of times I’ve looked up issues with specific applications, only to find out it’s a well known problem that the maintainer refuses to take responsibility for despite being aware of and active, but other users supply several options for workarounds.
