[Bug 809583] [NEW] Textures are flipped vertically in kwin compositor

 

Public bug reported:

Steps to reproduce:
1. Start kubuntu on an intel system (EEE PC 901 in my case)
2. Make sure kwin compositor is enabled
3. Observe flipped windows. They are rendered as flipped, though real mouse-sensitive widgets are in their correct places, so it's even difficult to disable compositing without command line.
