Hello – I’ve just upgraded to a 2.4 ghz imac, 2gb RAM, Radeon HD 2400 graphics card, OSX 10.5.6. I’ve been trialling Photoshop CS4 and occasionally notice a random bug – (I haven’t been able to identify what sets it off – sometimes just making a layer invisible then visible, or selecting an area with the lasoo) – transparent (ie. grey/white chequered) rectangles start appearing as the screen redraws, and parts of the image start blurring and shimmering. I quit, restart, and all is fine again for a few hours, and then it starts again?! The files I’m working on are by no means massive – 35MB . Any idea if it is a RAM or graphics card or Adobe or Mac or ? issue?! I’m also using an old Wacom with current driver – I haven’t experienced this problem in any other program, though. Many thanks!
