I have read the Tech note:GPU and OpenGL Features and Limitations in Photoshop CS4, but do not see the issues I encountered on my set-up.
I have had to switch off OpenGL because I was regularly getting the following issues:
Using marquee tool in normal mode, clicking on canvas created fixed sized selections. Repeated clicks created different fixed size selections.
Attempts to transform selection created increasingly-large selections that had only the bottom-right handle on canvas.
Free transform tool – exactly the same issue as transforming selections. Dragging layers between windows not working.
New window arrangements not working until selected at least twice. Regular crashes.
I have cleaned my system with Applejack, trashed & rebuilt prefs, reinstalled but problems persisted until OpenGL was switched off.
My card is OpenGL compatible – ATI Radeon HD2600 with 256MB RAM. My machine is an iMac 2.8GHz with 4GB RAM.
