Jonathan,
Sorry to bother you with this, but there seems to be a bug in
the 'render-to-disk' mode (or, in my case, to XMS), which more
or less clobbers the calculated image.
This kicks in only if used *directly after startup* of
Fractint and only in a certain range of image line lengths:
Everything is ok on my machine up to 2048; the first undisturbed
picture I get after that is at 4800 x 3600 (haven't checked precisely,
this is simply the first higher disk mode in my fractint.cfg that
works again).
Switching to one of the "bad" modes after having already
finished/interrupted another image makes the bug disappear
(even an internal start with <insert> doesn't change this).
Almost forgot:
Fractint 20.04 patch 4 on MS-DOS 6.22,
(very) old Intel Pentium MMX 233 MHz.
The par below isn't really necessary, but that's what I used
checking through the offending disk-mode resolutions.
Regards,
Gerald
