Marking fixed as EGL is the default backend now in 10.17 and the problem is not reproducible with that.
...bad argument, if I ever seen one.
The bug is likely still there in the other backend, so until that codepath gets trimmed, instead of just made non-default, the bug remains valid, if no longer a priority.
