Occasionally, I'll try to alt-tab and find that nothing comes up because the window previews process has crashed or gotten into some other unrecoverable state. If I go into dconf editor, and toggle 'enable-previews' in 'org/ubuntubudgie/budgie-wpreviews' off and then on again, it fixes whatever was wrong or restarts the process and everything is fine again.
In trying to figure out what's going on, I found this in my system journal:
Dec 11 16:20:13 hostname previews_creato[1819]: The program 'previews_creator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 7784 error_code 3 request_code 20 (core protocol) 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 GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
This appears to happen every 1-3 days on my system and seem to correspond to when the program breaks. I'm running Solus 4.4 Budgie, and using the window previews package in their repository.
