While that may be the case for you, I use acroread daily as part of my work, and all of my main machines have Radeon hardware 99% of the time. I've never even once encountered the problem you describe, and if I had, I'd immediately assume it to be an acroread problem, or poor interaction between Acroread (which is a Motif application), and the window manager. >+Also, just to note - I use Acroread daily, and do not have this problem. > >Yes, so do I, and I only have the problem with the Radeon driver (this >machine is my only Radeon).

I use all applications _only_ maximized, so that isn't the case. >(b) Mike hasn't tried it in full screen mode with the Radeon driver (or if >he's tried it with another Radeon card, then not on the same machine I >use). Again, I only use applications maximized. You were quite clear about it being maximized also. >(c) I'm imagining it. > >So any suggestions, verification, etc., would be welcome. If it is >plausibly an acroread bug, I will certainly file it with Adobe. I never claimed you're imagining it. I just classify the problem as a non-video-driver problem. The video driver draws graphics on the screen. Doesn't matter what video driver you're using, the problem you are describing is at a layer that is not internal to the video driver used. It is at a higher level which is outside X, namely the window manager and/or libraries the application uses. You can continue to think it is a Radeon driver bug if you like, but that wont get you any closer to a solution. -- Mike A.
