hi,
just installed blender 2.49b 64bit on opensuse 11.3. It runs fine but there seems to be some problem when showing the render window. Usually, the first time, it shows ok. I like keeping the render window open on my second screen. But sometimes it fails to get focus and flashes in the taskbar. I have tried disabling desktop effects (using kwin) but it doesn’t help. Simply switching back and forth between the blender window and the render window suddenly makes the mouse cursor hang for a 5 secs so I can’t do anything but wait.
Would this be a known problem? 
My 3D acceleration works fine using the Nvidia binary driver. I read about similar problems in the past and tried running “blender -w”. Although it removes the (similar) hang up at startup, it exhibits the same problem with the render window. When using a view or fullscreen render output, there is no problem. I am using multicore rendering (4), dunno if that matters…
anyone knows a solution?
thanks
