Bug? Unexpected behaviour Channels panel

Recommended Posts

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.

This might be unique to Mac, as I do not see this behavior on Windows.

For future reference, reducing the file's width to around about 2000px usually cures this (rather unhelpful) error code


Due to the fact that Boris Johnson is now our Prime Minister, punctuation, spelling and grammar will never be worried about ever again.  We now have far bigger problems to be concerned about.

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.
