BACKENDS: Linux (OPENGL/SDL) - BadMatch crash when switching from windowed to fullscreen

[dafioram]

SDL: 2.0.7
OS: Ubuntu 18.04
Lastest scummvm

When switching from windowed to fullscreen sometimes the game crashes with BadMatch errors.

I can't reproduce this, it happens occasionally when switching from windowed. I think it it more likely to happen if the game has been running for a while windowed. I was playing riven at the time.

Here is two of the errors:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  141 (RANDR)
  Minor opcode of failed request:  21 (RRSetCrtcConfig)
  Serial number of failed request:  1146968
  Current serial number in output stream:  1146968

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  141 (RANDR)
  Minor opcode of failed request:  21 (RRSetCrtcConfig)
  Serial number of failed request:  168885
  Current serial number in output stream:  168885

Would probably need to run ScummVM from gdb i.e. gdb ./scummvm, then type "run" at gdb command line and play game as normal. If / when the crash occurs you will be back at the gdb command line and can do "bt" to get a backtrace on the assertion / crash to see where this is triggered from and what the values of the function call stack is... that might allow debugging of this.

Is this still an issue with 2.7.1?
