Bug Report Crashes on startup 'BadWindow'

At one point OBS started crashing occasionally on startup. Now it does it almost every time. For a while I could fix this by rebooting my computer, but now even that is not helping. The window will appear very briefly and then close. I am using Linux Mint 17.3 Cinnamon 64 bit. Here is the most relevant portion from the bottom of the terminal output:


error: X Error: BadWindow (invalid Window parameter)
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 90 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.)

I figured out what is happening. I have 2 video sources. One is a Screen Capture and the other is a Window Capture which displays a chat window of top of the screen. When I launch OBS, it automatically loads my previous settings including the Window Capture. If that window is not open at the time I start OBS, it will crash. If I make sure to open that window first, then OBS will not crash. So for now if I just make sure to open that window first I am all good.
