Could you please verify, if this is related to bug 0011321 ? (see description of that bug)

Might also be related to bug 0011578 ..

I suspect this being a LCL bug rather than a glscene bug ..

Could it be caused by graphics card / driver?
I've read similar issues here: (not Laz. related)$

My suspicion is also a Graphics driver, but latest drivers (for Vista) didn't fix it.

I am not at all knowledgeable enough on the subject to know if any of those bugs would be related. (They also don't have screenshots... and somehow I think that it describes it much better).

If you change your Vista Appearance back to Windows "Classic" theme (or whatever they call it on Vista) it works correctly!

Won't call it a fix, more a workaround, but it is definitely a GLScene issue.

Related bug 0013235 seems fixed. Please retest with a recent lazarus version (svn or nightly snapshot).
