SUMMARY Using Image > Separate Image... with the enabled option "Output to color, not grayscale" confuses the separated channels if the image uses anything else than 8-bit per channel. All color models I tested (RGB, LAB, CMYK) produced the issue. STEPS TO REPRODUCE 1. Open an image that uses 16 or 32-bit per channel 2. Use Image > Separate Image... and enable the Output to color checkbox 3. Hide the original layer(s), inspect the separated layers OBSERVED RESULT Channel layers can be swapped or empty, so the full color image cannot be assembled correctly. EXPECTED RESULT Correctly split channels, same as with 8-bit depth. SOFTWARE/OS VERSIONS Tested in master (git 179649c) and 4.2.7.1 from distro repos, both showing the same issue. ADDITIONAL INFORMATION Small usability gripe - Using the new "Activate the current channel" option that's present in master will give all channel layers the Inherit Alpha property, so they can't be seen unless there is a solid layer behind them.
