Bug ID: 384884
Summary: Crash on screen resize

Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
>From the trace I'd say I'm running glDeleteProgram() without a context?
I'm not fully sure why it's not reliably reproducible. I've spent a big chunk
of the day switching screen scales (and so geometry) constantly, and hit this
twice.
Do we sometimes "leak" the doneCurrentContext() and it depends on what it
happened to have rendered last?
I made the obvious patch, and not seen this since.
