Status: RESOLVED DUPLICATE of bug 1694734

(Firefox :: Theme, defect)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Windows 7, Nightly 88. Regression is approximately four updates ago: so about two days (I update twice a day)

STR

• enable ui.systemUsesDarkTheme = 1
• enable built-in light or dark theme (not default)

Actual results:

• the min/max/restore/quite icons are obscured behind the top panel

Expected results:

the min/max/restore/quite icons should not be behind the top panel

see attached image: my mouse pointer (not shown) is hovering over one of the buttons and reflecting a blue glow

STR: enable ui.systemUsesDarkTheme = 1 is not needed. The problem also happens on Alpenglow theme

Comment 2

[Thorin [:thorin]]

OK, confusing myself. I think this is what happens

when ui.systemUsesDarkTheme = 1

• all themes cause the issue

when - ui.systemUsesDarkTheme = 0 (default: hidden pref)

• only default theme seems to be OK

Can you please run mozregression to find out what broke this? You can set prefs for mozregression directly from the commandline.

Regression is Bug 1594132 .. probably a duplicate of Bug 1694734 .. my STR was to just flip between default and dark (no pref) .. windows 7
