As pointed out in bug 455601, the driver runs out of memory if using EXA with only 32MB VRAM, so reducing virtual screen size or colour depth are workarounds.
This might be less of a problem when using KMS, where video memory is handled by a memory manager. ** Summary changed: - certain windows drawn garbled when compiz is disabled + (EXA and 32MB) certain windows drawn garbled when compiz is disabled -- (EXA and 32MB) certain windows drawn garbled when compiz is disabled https://bugs.launchpad.net/bugs/426582 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
