STR (tested on Win7, Nightly 42.0a1 (2015-07-29), fresh profile):
1. Set white devtools theme.
2. Open page data:text/html,<body><script>var str='<div>';for(i=0;i<70;i++) str='<span>'+str;document.body.innerHTML=str;</script>
(or attached page)
3. Open devtools->Inspector (Ctrl+Shift+I)
4. Hide sidebar
5. Type "div" (without quotes) in field "Search with CSS selector"
RESULT:
Breadcrumbs were scrolled to the <div> label, but all visible <span> labels are white instead of black. (video in URL field)
EXPECTATIONS:
<span> labels should be black
NOTE:
There are also more STRs like this; some of them don't result in all visible labels having white color but rather 1-2 labels having white color instead of black

Thank you for the video and STR.
I can't reproduce this on OS X or in a 32-bit Windows 7 VM.
Can you please verify that you still see this on your end?
Спасибо большое!

Yes, it's still reproducible. After text labels become white, then in ~5 seconds they become black again
I figured out 3 things:
A) I can trigger similar issue in ESR 38, but rectangles with text lagels become dark (not black)
B) If I stop JavaScript in Debugger (in Browser Toolbox) after text labels become white, and then wait ~5 seconds, they still become black. That means that it's not JS that caused this issue
C) If I disable hardware acceleration then I don't see this issue.
So, I have a question:
Are graphical issues of this kind never fixed? (because "user must update graphics drivers")
Slightly different STR with the same result:
https://dl.dropboxusercontent.com/s/0g1u61n2k2x5eba/Inspector%20breadcrumbs%20labels%20are%20white%20instead%20of%20black%20%28always%20reproducible%29%202.webm?dl=0
Summary: Inspector breadcrumbs labels are white instead of black (always reproducible) → [HWA] Inspector breadcrumbs labels are white instead of black (always reproducible)

Thank you for the updated STRs / video.
I'm still on the road, and it's super hard to reproduce this in a VM, even with hardware acceleration turned on.
I'll have access to a real Windows box in a week, and should be able to further dig in then.
> Are graphical issues of this kind never fixed? (because "user must update graphics drivers")
Not never, but glitches like that do tend to take longer to fix. :(
Status: UNCONFIRMED → NEW
Ever confirmed: true
Here's my about:support page. Request additional info if needed.
I may be unavailable for very long time though. In this case, this bug should be closed.

I can reproduce this bug as follows.
1) Open any pages (e.g. bugzilla.mozilla.org)
2) Select any elements in such a way as to [>]button(.scrollbutton-down) is displayed. (e.g. Narrow window width, Having a lot of child elements)
3) If .scrollbutton-down was changed disabled in the selection timing, breadcrumbs label font color turns white for 5 seconds.
Is this behavior designed? If so, it's a strange design specification.
magicp, yes I knew about these steps but decided that they are unreliable...
(1) It should be "fixed" for you if you uncheck "Use hardware acceleration when available" on page about:preferences#advanced -> "General" tab
(2) Please open menu (≡)->(?)->"Trougleshooting information", save that whole page (or at least "Graphics" section) and upload here. That would be helpful

Is this issue caused by OMTC (OffMainThreadCompositing)?
Could you try as follows
[about:preferences#advanced]
"Use hardware acceleration when available" = true
[about:config]
layers.offmainthreadcomposition.enabled = false
Probably, Window 7 VM and Mac OSX blocks(not use) OMTC

@magicp:
Yes, you are right! With HWA on and OMTC off this does not happen! (is OMTC a part of HWA?)
// I actually tried disabling OMTC without browser restart (before reporting this), because OMTC haven't required it some month ago. And haven't got positive results. So restart is *necessary*
> Probably, Window 7 VM and Mac OSX blocks(not use) OMTC
This is very true. Markus Stange said in bug 1202714 that he can't repro it on Mac OS.
