Bug Report [Still unsolved] Regular crashes due to an X Window System error

I'm running Manjaro Linux, using XFCE and running OBS 0.12.2 (linux) and I can't seem to find anyone else with this error. OBS usually crashes when I'm changing OBS's display settings. Here's my output from running with a console: http://pastebin.com/xqFLVZgP and here's the log file for that particular crash https://gist.github.com/anonymous/d6f5e188b05ca8866ab2 .

I've asked around on the IRC but no-one knows what to do. My console output seems to suggest a bug in the software. I've installed it from the AUR repository in Manjaro.

Thank you for your attention, any help would be greatly appreciated.

I'm wondering if it's an Xfce issue. I run Xubuntu, and I'm getting similar errors whenever I launch OBS. Sometimes I have to launch the program five or six times before it decides to not crash when opening, changing settings, or configuring scenes. It's getting annoying to say the least, and after installing 0.13.1 today, it's still happening.

Here's what happened when I opened the Settings window and tried to view the Output section:

Code: 
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 21603 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)

Oh, I see, run it as obs --sync. Okay...

Code: 
error: X Error: BadWindow (invalid Window parameter)
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 407 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.

Segmentation fault (core dumped)

The program window flashed quickly on the screen and disappeared. Note the error code? Let's try again...

Code: 
error: X Error: BadWindow (invalid Window parameter)
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 329 error_code 3 request_code 3 minor_code 0)

   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line

   backtrace from your debugger if you break on the gdk_x_error() function.)
QObject::~QObject: Timers cannot be stopped from another thread
Segmentation fault (core dumped)

I'm starting to see a pattern. Could Xfce be causing these problems?

I've got the same problem on Ubuntu 16.04. I just follow @ZeroFossilFuel's post and it works for me.

just copy the command below and past it to your terminal. then run your OBS again.

Code: 
rm -rf ~/.config/obs-studio/

It's been a while since I revisited this bug but I will test it later today. Needless to say, if it really is fixed I will be dancing in the street! :)
