0.8.22R9 has been out of date for quite some time. I would make sure you're running the latest drivers for your VIA chipset (very important) and video card as well. By latest, I mean the latest "certified" drivers. If those don't fix the problem, try the latest "latest" drivers.
If those simple steps don't fix the problem, you can start with some simple troubleshooting procedures, followed by some not-so-simple troubleshooting procedures, followed by a source code review (which is sometimes less work than the troubleshooting procedures).
