With your new patches, I'm not experiencing any crashes, and the terminal displays the “cms!” message, confirming that it's working. Thank you. It also works when I use my own monitor color profile instead of the generic “sRGB.icc” and “WideGamautRGB.icc” files. Here's an example of the terminal output using my profile (Dell_1886_LUT_4.icc): $ CIN_CM_PROFILE="/usr/share/color/icc/colord/Dell_1886_LUT_4.icc" /home/paz/cinelerra/cinelerra-5.1/bin/cin /home/paz/wide-gamut-tests/P3-sRGB-color-ring.jpg /home/paz/wide-gamut-tests/R2020-P3-color-bars.jpg Cinelerra Infinity - built: May 16 2026 10:19:56 git://git.cinelerra-gg.org/goodguy/cinelerra.git (c) 2006-2019 Heroine Virtual Ltd. by Adam Williams 2007-2020 mods for Cinelerra-GG by W.P.Morrow aka goodguy 2003-2017 mods for Cinelerra-CV by CinelerraCV team 2015-2026 mods for Cinelerra-GG by Cinelerra-GG team Libav version: Lavc62.28.100 Cinelerra is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions.

CinGG also works when started from the KDE launcher—which was one of the things I suspected was causing the issue... To include these features in the manual, I’d like to ask a few questions to clear up some doubts, but I’ll post them in a separate thread.
