[Bug 541430] [NEW] Occasional corruption after screen resize due to bogus GL viewport

 

Public bug reported:

Binary package hint: compiz

Source package: compiz 1:0.8.4-0ubuntu2

1) Ubuntu 9.10

2) compiz-core compiz 1:0.8.4-0ubuntu2

3) The screen should always continue updating properly after the screen
size changes.

4) Sometimes after screen resizes the screen becomes corrupted and stops
updating.

I've tracked this down to compiz caching the values passed to
glViewport() but neglecting to update the cache in one path, leading to
incorrectly short-circuiting later glViewport() calls. The attached
patch fixes this.
