I've just tried two glxgears at the same time and I am seeing utterly strange behaviour with two glxgears running, where sometimes if I move one it will leave bits of gears behind (sometimes a whole frame), and sometimes corrupt my desktop background image (and I mean really corrupt; not a redraw error) with bits of white, indicating a write into an off screen area; the bitmap is tiled and if I refresh the whole desktop the corruption shows up in all of them; I have to upload a new background image to make it go away. Also if I leave them still only one of the glxgears windows will animate at once; a bit of animation from one, with nothing from the other, and so on back and forth pretty much randomly (at first I thought it might be related to window focus, but it's not). I see this with the SET_SCISSORS patch, and also with the old behaviour, both with and without pageflipping enabled. For experimentation I inserted the RADEON_WAIT_UNTIL_2D_IDLE() that I tried the first time and it happens with that too. (on my system glxgears behaves quite oddly with pageflipping enabled even with only one; it has brief periods of seeming to animate slowly backwards, but shows no significant change in framerate - it is the only app that I've tried that behaves so strangely) I have some suspicions. Amongst them is the fact that the 2D drivers emit clip rectangles too, I notice. I will have a look at it and see if I can some of fix these problems here. -- Tim Smith ([EMAIL PROTECTED]) "A fray!!!!" -- Groo the Wanderer ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Caffeinated soap.
