@kisak-valve I upgraded from Xubuntu 16.04 to 18.04 and the sound is working now.
The bit about the launch options is still relevant, though.
Given that I tested PvZ with the -changedir launch command, it immediately crashed upon Shift+Tab'ing to bring up the Steam overlay, when I was in-game
Another issue is that it starts dropping the framerate a ton (below 30) whenever your on the plant selection menu, before starting a new level
There's also a thin single-color (such as green, brown, etc.) line that sometimes appears on the bottom- and right-side of the screen when in fullscreen, sometimes it's of the previous scene a couple of seconds ago
Though Alt+Tabbing out and back in clears it up (or not having fullscreen enabled prevents it, I'm assuming)
It works without issues since Proton 5.0-8.
A workaround is possible for eliminating plant selection fps drop though it could possibly a DRM violation. When the game is running, the game creates another binary called popcapgame1.exe in steamapps/compatdata/3590/pfx/drive_c/ProgramData/PopCap Games/PlantsVsZombies and then executing the majority of cpu time in this binary. Replacing the original PlantsVsZombies.exe binary with this one seems to solve all stutter problem. However, whether cloud save and achievement is still working is untested using this method.

The game runs well, but as far as I can tell, it seems like it's just using software rendering instead of being rendered by the GPU. For reference, I have an AMD RX 5600 XT, which is very well-supported on Linux. I would like to be able to use GPU rendering because it would allow my PC to run much more quietly while playing this game.
Hello @RedSoxFan04, please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.

after playing the game from 30 minutes to 1 hour. the audio speeds up (to a fixed speed), and starts randomly cutting. it only applies to the background game audio, not the audio effects like zombies sounds or peashooters
