GNOME Bugzilla – Bug 341018
"Lighten only" mode of Layer produces strange maps in image
Last modified: 2008-01-15 13:07:35 UTC
Motivation: I've several images of waterfall. I want to merge them down using "Lighten only" mode on 2nd and another layers to enhance efect of white motion blured water. Bug: Gimp produces strange residua maps on resulting image around areas where effect apply. Check out: http://www.tomasek.cz/stuff/20060501_7560.jpeg Original XCF file is: http://www.tomasek.cz/stuff/20060501_7560.xcf Bug is somehow hooked to "Merge visible layers" because if I save example image without "Merged" layer resulting jpeg is OK. Check out: http://www.tomasek.cz/stuff/20060501_7560a.jpeg Feel free to ask me for any other information that might help you fix bug. Thanks
This seems to be a bug in the assembly acceleration routines. Try starting the GIMP on the commandline with the "--no-cpu-accel" flag and the errors disappear for me. I can confirm this with 2.2.10 on a Pentium mobile, the problem seems to be fixed in CVS HEAD.
This also happens with 2.2.11 on a P4.

Yes, error disappear if I run Gimp with "--no-cpu-accel".

Please run gimp with the --verbose command-line and paste the result of the tests for processor instruction sets to this bug-report.

one question, i am having this same problem and i am wondering how you run The GIMP with these different things such as "--no-cpu-accel" thanks for your help.
