I don't know if this is good news or bad news. I grabbed the latest float-only source, dumped unpacked in in a clean directory in the current Mandrake, type "make", and ran it with boundary tracing. I couldn't debug your problem ... because there was no problerm to debug. Boundary tracing works perfectly for me.
Did you zoom in? Also, try SWT-027 in the default fractint.par file. I believe that before this last patch boudary tracing would lock up on the default mandelbrot, so you might be right about it being a video problem.
I wish I could see the problem, because it looks to me like it is easy to debug. I checked that the enum values North, East, South, West had the correct values of 0, 1, 2, 3, and checked that the macros were working. I'd just instrument the code each time the coming_from variable is set, and stop in the debugger the first time it is out of range. Then check the values used to calculate it. Alas, I can't see the problem, so I can't fix it.
Natalie has also seen the problem, so it isn't just me. 8-))
Maybe I need to try on my laptop? What machine are you running on? Perhaps the video driver is making it hard for Xfractint to recover pixels from the screen.
I'm using my laptop, but I'm sure I've seen this problem on other machines. Jonathan
