Created attachment 8703658 [details] no-icons-in-developer-tools.png User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160103030302 Steps to reproduce: 1. Open developer tools. 2. Check that the light theme is enabled Actual results: No icons are visible in the developer tools tabstrip, except for the selected tab. Expected results: Icons should be visible.
Forgot to mention that the bug doesn't affect my MacBook Pro Retina. It only shows up on my Win10 computer.
I've verified this is an issue with Hardware Acceleration enabled. OS: Windows 10 Pro, 64-bit Firefox: 44.0.2 (32-bit) GPU: AMD Radeon R9 380X (4GB) with v15.12 drivers This also affects the Reddit Enhancement Suite addon when using "night mode" (See this thread for more information: https://www.reddit.com/r/RESissues/comments/46be3r/bug_expando_icons_missing_in_night_mode/)
Is this only affecting the light theme? I wonder if it has to do with the CSS filter we are applying on the icons in light theme.
Status: UNCONFIRMED → NEW
Component: Developer Tools → Developer Tools: Framework
Ever confirmed: true
If I switch to dark theme, the icons appear correctly from what I can tell.
(In reply to Chris from comment #5) > If I switch to dark theme, the icons appear correctly from what I can tell. Michael, can you confirm that the icons come back if you disable hardware acceleration as in: https://www.reddit.com/r/RESissues/comments/46be3r/bug_expando_icons_missing_in_night_mode/d04dp5z? I suspect it's due to this line and the CSS filter somehow not applying properly: https://dxr.mozilla.org/mozilla-central/source/devtools/client/themes/toolbars.css#991. It's looking like we can make this depend on Bug 1229375.
Depends on: 1229375
Here's a screenshot comparing the light/dark themes of the developer console: http://i.imgur.com/bKEjC6A.png
I don't have access to my windows pc before next weekend. The GPU is, as with the others affected by the problem, a AMD R9 380 (just 380, not 380X). The icon issue only affects the light theme. Switching to the dark theme worked as a workaround for me.
Disabling hardware accelerating fixes the problem for me.
(In reply to Michael Eischer from comment #9) > Disabling hardware accelerating fixes the problem for me. OK, thanks. Sounds like this will be fixed by Bug 1229375
Leaving this open so we can re-check after Bug 1229375, but no immediate action needed from devtools here
Priority: -- → P3
No issues for me anymore with Firefox 52.0.2 (32 bit) on Windows 10, AMD Radeon R9 380 card and the latest 17.4.1 drivers with hardware acceleration enabled.
