No magic. I assume there's something bad happening between glib and the FreeBSD memory allocation routines, but whatever it is carried across 5.3 to 6.2. I'm pretty sure I logged a bugzilla case, but in the end, I switched to a linux platform and lost interest. I get the feeling that the GIMP devs don't use FBSD and as long as it builds and runs, they're not all that interested in what seems like corner cases. 2. You could try setting undo level to 0 at the risk of not being able to recover from any mistake 3. nope, at least not that I've found 4. nope
Don't bother with film-gimp or whatever they're calling the project these days. It does HDR, but their big memory handling is even worse. Turns out that the images projected in theaters are actually not all that hi rez. Your eye fills in the missing spots frame by frame. If you built KDE for your desktop, you might want to check out Krita as an image editor. Last I looked at it (which is maybe 9 mos), I still liked the GIMP better, but it (krita) handles images completely differently, so it might be worth a shot. Didn't get a chance to run any of my scans through it. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
