My game would fail to launch there would be a flash and the game would attempt to draw a window. After turning on logging I saw something like this.

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  ### ()
  Minor opcode of failed request:  ### ()
  Serial number of failed request:  ###
  Current serial number in output stream:  ###

I started debugging and chasing down random forum posts relating to nvidia driver issues, xrandr errors, reinstalling divers.

For me, somewhere along the way the graphics settings were changed. I had to run an older version of the game in beta mode and it was a whole thing.

Bottom line, I went back to the last known good config where the game would launch then changed the system settings from "borderless" to "fullscreen". That finally made the reproducable error of a failed launch go away. There is probably an .ini file in the wine space I could have editied too.
