Summary: ChimeraX bug report submission → Attempt to retrieve context when no valid context

comment:2 by Tom Goddard, 4 years ago

Resolution: → can't reproduce
Status: assigned → closed

Trying to draw the status line on an expose event. The code has already successfully made the OpenGL context current, but then it fails trying to render. This is on Linux run under Windows (WSL = windows subsystem for linux). Maybe the expose event is not in the main thread. Would get a lot more bug reports if that was the case.
