925322 - Display of controls inside panels in Firefox 27

Status: RESOLVED DUPLICATE of bug 923542

(Core :: Graphics, defect)

Controls disappear in panels on GNU/Linux.

I'm using Nightly on Debian GNU/Linux. For a few days, each time I open a panel (download manager, panel to enable plugin, panel to get info on page certificate…), its controls disappear when I move the mouse hover them.

I'm using minimalist window managers, like Fluxbox and Awesome. People don't seem to have the same problem with Gnome.

I tried several builds from Tinderbox. The latest to work is 1380708121 built from http://hg.mozilla.org/mozilla-central/rev/e3c84e9f2490. The next one, 1380728654 built from http://hg.mozilla.org/mozilla-central/rev/aca286bc0013 is broken.

I have the same bug with 32 and 64 builds.

Here's my graphic configuration:

Adapter Description: Humper -- Chromium
Device ID: Chromium
Driver Version: 2.1 Chromium 1.9
GPU Accelerated Windows: 0/1 Basic Blocked for your graphics card because of unresolved driver issues.
Vendor ID: Humper
WebGL Renderer: Blocked for your graphics card because of unresolved driver issues.
windowLayerManagerRemote: false
AzureCanvasBackend: cairo
AzureContentBackend: cairo
AzureFallbackCanvasBackend: none
AzureSkiaAccelerated: 0

Don't hesitate to ask for more informations.

I confirm this bug happens on my Linux config, too: Ubuntu 12.04 LTS + i3-wm on a ThinkPad x220 (Core i5 + Intel GPU).
Here’s my graphic configuration:

Adapter Description: Tungsten Graphics, Inc -- Mesa DRI Intel(R) Sandybridge Mobile
Device ID: Mesa DRI Intel(R) Sandybridge Mobile
Driver Version: 3.0 Mesa 8.0.4
GPU Accelerated Windows: 0/3 Basic
Vendor ID: Tungsten Graphics, Inc
WebGL Renderer: Tungsten Graphics, Inc -- Mesa DRI Intel(R) Sandybridge Mobile
windowLayerManagerRemote: false
AzureCanvasBackend: cairo
AzureContentBackend: cairo
AzureFallbackCanvasBackend: none
AzureSkiaAccelerated: 0

I’m tempted to qualify this as “major” because it makes it difficult to confirm/validate a panel. Pinging my co-workers to see if they have the same issue…

Probably cause by bug 916034. Probably dupe of bug 923542.
