First let me congratulate you guys for writing this excellent program, before I start telling you what I can't do :=)

Well this is my problem. I wondered if dosbox could run fractint. Much to my surprise it does and even can get color cycling working at high resolutions but whenever I switch out between the text and graphics mode somewhere on the 51 line the image gets corrupted.

Can this be solved / worked around.

these are the versions I am using

DosBox v0.74
Dfend 1.3.5

and the latest version of Fractint 13 February 2012 - Fractint 20.04p12

Anyone have any idea what goes wrong?

The glitched line in VESA modes is fixed in SVN, so you could try using an SVN build.

The low-res VGA and register-tweaked VGA modes show more significant corruption of the graphics when returning to graphics mode from text mode. I have a workaround program for the issue, but there's no need to bother with it if those modes are of no interest.

Yes this is a known bug... I made a post a while back but there are workarounds. Just change your machine type to svga_et3000 or svga_et4000 and it will work properly. It has been tested by me. As far as I know this bug might be hard to fix...
