screenshot with broken rendering
We omitted to fallback on colorlogicop as we don't know yet how to do that. The fallback might slow down blender. But it was working correctly on different version of driver, with exactly same hardware. Was fallback enabled before? If yes, then it didn't slowed down Blender, it was OK. With this bug Blender is almost unusable. r300 history is sometimes hard to follow, but i don't remember seeing anythings about GL_COLOR_LOGIC_OP in r300 before, maybe somechange in core mesa lead us to not fallback. Anyway i have commited yesterday the fallback stuff, i haven't tested with blender as i don't know at all how to use this. So please try with cvs r300 driver and report if it fixe the issue you are seeing. I will tackle color logic op after i am done with r300 cleanup and smooth line, thus we don't fallback on it. To test it, please install blender, and perform following steps: - start Blender - move mouse cursor somewhere in the middle of the screen - press "b" once - move mouse Incorrect behaviour is visible on screenshot - lots of lines. Correct one is selection rectangle just like in any other editor (like Gimp). PS. ESC exits selection mode, "q" quits blender I don't have this problme with rectangle but with lasso selection, drawing are kept in screen until some stroke... In some case (with 'limit selection to visible' activated, not in wireframe mode and in vertex selection mode only) the rectangle select hazardouzly vertex, not all the vertex inside the rectangle selection, as you can see in these screenshots : http://popolon.free.fr/Selection_bug.png upper selection in solid mode (the bug in the selection) lower selection in wireframe mode (all the vertex are selected). The bug does not occur in whole software fallback. Popolon, are you sure that you are using r300 with 6.6.2 driver? I can't reproduce the bug with lastest cvs (with my lastest commit). Have you tried with lastest cvs ? We now fallback and thus use software rendering for this. I used cvs from august 15, (or 25 ??) I've a segfault on every 3d applis (with acceleration). Didn't verify recent dependencies It is fixed in current Mesa CVS. Has this bugfix been put into Mesa 6.5.2 release? I just installed new binary packages of Mesa and Radeon driver and bug is still there :( I recompiled Mesa-6.5.2 and bug is fixed, sorry for false alarm, probably binary package is broken. |
