I installed a few different themes to see if it was a theme error, but they all have the same results.I'm not sure if this is a tweak for the Slimjet dev to work on so that the matching wallpaper is displayed, but in the meantime, couldn't that color be changed to black or at least a dark gray? (color #333333 or #222222) I don't really need a matching background, a simple solid dark background would do the job. On a positive note, I'm glad the useless "warning" label is gone!
I always run incognito. I have Iron on Windows, and Chromium on Linux, and they are set to launch "inconito". They show the theme wallpaper when in incognito.
Slimjet is already looking to be an excellent replacement for Iron, but the bright white background has got to go.
Cheers!
No biggie...I can live with that.
