If I uncheck a colour channel being the only one, other than alpha as far as I know, Krita crashes (possibly because the channels start disagreeing with each other because there is nothing for the Alpha layer to shade in or something). The picture also mysteriously turns into a grayscale when you have one channel open, even though goes white-to-C/M/Y when you have two colour channels open. Not sure if it is or is not meant to happen, though.
Hi Jordan, it sounds similar to Bug 395301. Please, could you check with the latest build at: https://binary-factory.kde.org/job/Krita_Stable_Windows_Build/ (stable) or https://binary-factory.kde.org/job/Krita_Nightly_Windows_Build/ (nightly build)? Thanks
I'll mark this bug as a duplicate. If you still encounter the bug in the builds linked by mvowada, please reopen the report :) *** This bug has been marked as a duplicate of bug 395301 ***
