- I seem to have fixed ths issues with the main preview widget. It seems you just need to set the right window attributes to stop it from breaking. Though when opengl is enabled, there appears to be a weird background glitch in the Qt stuff -- I'm not entirely sure what's going on. Bug in Qt? Also fixed the layout issues, and the widget now properly resizes and centers in to its parent widget. - Prevent the render loop from accessing data if the data isn't valid. Because obs->data is freed before the graphics stuff, it can cause the graphics to keep trying to query the obs->data.displays_mutex after it had already been destroyed.
