Sorry to insist, I don't know much about XaAES, and I'm totally lost 
with your test environments and versions, but the following point may be 
important.

In ARAnyM 0.9.8 and previous versions, the VDI function vro_cpyfm() was 
buggy because a bug inside SDL for Intel x86. This was about an 
assembler routine that didn't backup an internal flag in the CPU.

For me, using ARAnyM 0.9.8 on Windows XP, this problem caused the 
following effects :
- EasyMiNT boots well into XaAES
- I open a file window and move it to bottom-right
- Quickly, the window contents is filled with a buggy bitmap (sometimes)
- ARAnyM crashes promptly

This bug caused a random memory overwrite. For me the windows displayed 
rubbish or even crashed, it would be reasonable to think that this bug 
could produce the transparent window effect you experiment.

This problem has totally been fixed in ARAnyM 0.9.9.
So if your problem is still here with ARAnyM 0.9.9, it is something else.
