Jeroen Posted April 18, 2019 Share Posted April 18, 2019 This is an issue about the channels panel, looks like a bug to me. In 1.6, selecting a single colour, with alpha deselected, shows a B/W image, presumably of the colour channel. Same with 1.7 beta. However, adding alpha gives a monochrome image of the proper colour in 1.6, but a fully coloured image in 1.7 beta. If I add another colour instead of alpha, in 1.6 I get an image with the proper color mix, in 1.7 beta I again get a fully coloured image. I have reproduced this at will with any .jpg I tried. For some reason, uploading a file failed with -200, so no example, but I do not think it makes a difference. Link to comment Share on other sites More sharing options...

If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time. Link to comment Share on other sites More sharing options...

Staff Gabe Posted April 30, 2019 Staff Share Posted April 30, 2019 Hi all, Sorry for the delayed reply. This seems to be caused by the "Hardware Acceleration: Metal" and Display: Metal in the Preferences > Performance. With Display set to OpenGL, it should be fine. I will log this with our developers. Thanks, Gabe. Link to comment Share on other sites More sharing options...
