[osg-users] Bug: hang when closing all windows except the last opened (Mac OS X / Win 32 / SingleThreaded)

[Stephan Huber]

Hi Robert,

I tried to prepare the mail regarding the threading issues on Mac OS X 
and I found a possible new bug: (use the modified osgcamera-example from 
my previous mail) The modified example opens two windows on the 1st screen.

If I close the left window first, the rendering stops in the right 
window. If I close the right window first, the rendering continues in 
the left window. It seems that the context of the right window got 
invalidated somehow, because if I resize the right window I get 
pixel-garbage.

If I create more windows and close all windows except the very right 
one, the rendering stops again. So I booted Windows, did a svn update 
and tested it on windows. It hangs/stops rendering also, but with many 
open-gl-error-msgs in the console (invalid operation after xyz).

This bug shows up only in SingleThreaded-Mode: osgcamera -2 -s cow.osg

cheers,

Stephan
