Depth cue color sometimes mismatches background color

[olibclarke@…]

The following bug report has been submitted:
Platform:        Darwin-18.2.0-x86_64-i386-64bit
ChimeraX Version: 0.9 (2019-02-01)
Description
Hi,

It seems like the depthcue color upon loading defaults to whatever was last used, sometimes conflicting with the background color. E.g. I just loaded up with a white background and initially the depthcuecolor was set to black - I had to manually change it to white. However, when I manually change the background color using setbgcolor, the depthcuecolor changes correctly, so I'm not sure what's going on, it seems like a glitch of some sort. I have fixed it for my setup by manually adding set bgcolor and lighting depthcuecolor commands to my startup preferences.

Cheers
Oli

I don't understand your explanation "It seems like the depthcue color upon loading defaults to whatever was last used..." What does "upon loading" mean? Do you mean when ChimeraX starts? The depth cue color from the last time you ran ChimeraX is not remembered.

The background color and depth cue color are two different settings. But there is a bizarre behavior that might be tripping you up. When you set the background color (set bgColor white) it also changes the depth cue color to match the background color if the depth cue color was the same as the background color when the command was run. If the depth cue color was not the same as the background color when the command was run then the depth cue color is not updated.

I mean when I start ChimeraX.

I don’t know why it is happening, I have just noticed a number of times, I load chimeraX, load up a EM map and switch on soft lighting. My default background color is white, but the depthcue color is clearly black, even though I did not alter it at any point during the session - this is directly after starting ChimeraX.

Fixed.

Depth cue color was not matching preference setting background.
