"BadDrawable" XError at startup with kernel 5.11.1
We've received a report in Arch Linux that xfwm4 4.16.1 crashes at startup after upgrading the kernel from 5.10.18 to 5.11.1. [1]
I can't reproduce it myself, but the X error provided by the downstream reporter is:
'BadDrawable (invalid Pixmap or Window parameter)'
(Details: serial 2655 error_code 9 request_code 155 (NV-GLX) minor_code 4)
Is this something fixable in xfwm4 or more likely to be a driver issue?
