nice, a texture leak... :-( it's probably sufficient to suspend/resume compositing in this case (shift+alt+f12) - do you have the blur effect enabled? - do you blacklist the lanczos filter? - (wild one) check your GPU temp (the GS is probably passive?), overheating memory can cause this "at random" - No blur effect, even if I enable it. My windows are transparent during moving, but nothing gets blured in the background even with enabled blur effect. - Where is the lanczos filter? - My GPU temperature is at 75°C and yes, it is passively cooled. But I think the temp is ok for a passive GPU. Next time I will try the shift+alt+F12 trick. I hope the keys are working...

It's probably not causing this, but not exactly "low" either (i use a passive 7600GT @ 45°C) While your GPU can stand this temperature for some time (the colder, the older ;-) it can cause trouble in the rest of your system, because your memory & esp. HDD can NOT live at this temperature for a long time (in case of the HDD: minutes ;-) and your CPU won't like it too much either. You should keep an eye on the general system temperature and consider improving the general box cooling (-> chassis fan) just for the records: crossing the mesa code, GL_OUT_OF_MEMORY is thrown unconditionally whenever the driver fails to provide a new framebuffer, for what reason ever. though it's the NVIDIA driver... Nevertheless we could add a check in GLRenderTarget Changing to wishlist to add support for handling GL_OUT_OF_MEMORY. Possible solution would be to disable compositing when running into such a situation, though I don't know how we actually could test such an issue :-) |
