In OBS 0.14.2 under Linux when moving the mouse across some objects, selecting something from a drop down(scene transitions) or working with the interface in general(for example settings) produces the following:

error: X Error: BadWindow (invalid Window parameter)
error: X Error: BadWindow (invalid Window parameter)
info: adding 23 milliseconds of audio buffering, total audio buffering is now 23 milliseconds
info: Update check: last known remote version is 0.4.0
info: adding 23 milliseconds of audio buffering, total audio buffering is now 46 milliseconds
The program 'obs' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 9490 error_code 3 request_code 3 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Segmentation fault (core dumped)

nvidia driver version: 364.19

I am happy to provide any more info/help debug this issue. This is ongoing since 0.13(I think)

1) Purge OBS Studio from your box:

$ sudo apt-get purge obs-studio

2) Remove any unnecessary packages:

$ sudo apt autoremove

3) Wipe the configuration files:

$ sudo rm -r ~/.config/obs-studio

4) Re-install OBS Studio:

$ sudo apt-get update && sudo apt-get install obs-studio
