I observe pretty much the same behavior on one of the two systems 
I'm trying Amaya. With the previous version 9.0 I could observe 
similar effects on the both systems (although the one showed 
somewhat better).

Both systems I test with run WinXP SP2. The difference seems to come 
from the graphics card and its driver. The one is NVIDIA GeForce2 
MX400 (it's ASUS V7100 Pro exactly) and the other is built-in Intel
adapter in GIGABYTE GA-8IG1000MK motherboard (and its VGA driver [1]).

Till lately I was able to reproduce these kind of "garbage
flickering" problems on the system with the NVIDIA video card too,
but now when I've installed the latest driver from NVIDIA it seems
to be working fine.

I speculate it is a graphics card driver problem related to some 
kind of bitmap caches but then it is happening only with Amaya. 
Could it be wxWidgets library problem?
