Graphics debugging with RHIDE (or RHGDB) will (should) work for the
VESA modes, if your VESA driver works correct. For instance I have
tested two different VESA drivers and both were buggy. The one
specail for my et4000 (tlivesa.com) did not support the
"Get Window address" subfunction correct and the second
(univbe51, probably the same as you), destroyed in some unusual
way the video memory when it shouldn't (VESA function 0x02
with bit 15 set in bx).
So this may you problem. An other try would be for you to run
RHIDE with the "-G 1" switch to use the second implemented
methode to save/restore the screen. See if that helps you.
And a note for all of you who want to have good graphic
debugging support. I am NOT a graphics programming guru.
If someone think, he has an better way to do that, please
contact me or look at the sources.
