I recommend turning on graphics acceleration in the > preferences, or just living with the glitch. Well canvas acceleration is practically unusable on som3 Mac (see Bug 419783). And it's not a visual glitch only, but functionality issue too. So I think at least one of these two should be considered a confirmed bug. -- You are receiving this mail because: You are watching all bug changes.
