730723 - Header icons of the aero thread pane may become invisible when changing to high-contrast themes

Status: RESOLVED WORKSFORME

(Thunderbird :: Theme, defect)

Description

[rsx11m]

While testing bug 730701 I ran into this when using high-contrast themes.
Note that both D2D and ClearType are switched off on this machine.

In all high-contrast themes but High Contrast White the icons are not visible.

Judging from bug 588007 attachment 546791 [details], this seems to have initially worked at the time the patch was developed but has regressed since, or the specific settings make the icons disappear. This also applies to the 10.0.2 release.

Did you restart Thunderbird in between trying these out?

Good point, I didn't... :-\

Restarting Thunderbird resolves the issue indeed as long as I don't change the desktop theme after that (in which case I have to restart again to get any color changes effective).

Is there any way to avoid that? The menus and other items pick up a desktop-theme change immediately, just those icons won't (mostly a discovery thing that you'll have to restart before seeing the "real thing").

This should be solved with bug 940625

With using inverted icons on dark backgrounds this issue should be solved.
