Hi, I am developing an OpenGL application with its own scene graph that also embeds Coin3D to perform rendering of VRML objects. Previously everything has worked perfectly on my NVidia GeForce2 card, but when I run it using XFree86 v4.3 on my Radeon 9000 I get flickering textures on my VRML models. The flickering only occurs within my application and not when Coin3D is used to render the model standalone - so perhaps I've messed up something? I've seen posts that describe how to use R200_NO_TCL=1 in order to avoid this, and when I try it the textures stop flickering (but the rendering jumps around and goes crazy - perhaps this is my fault and points toward a bug somewhere else?) Anyway, rather than hack my app to work using this switch, could someone explain to me a bit about why this bug happens in the first place and what I can do to avoid it? Have I allocated too many textures or are they too large? Or does this problem disappear in the latest CVS and I'm best off just upgrading to this? I've gone through all the mailing lists and Google and can't find anything except to "just use it".

Current CVS is always worth a try. :) Beware that it currently needs a Mesa CVS checkout as well, I'm not sure what the status of binary snapshots is. -- Earthling Michel Dänzer | Debian (powerpc), X and DRI developer Software libre enthusiast | http://svcs.affero.net/rm.php?r=daenzer |
