Description rkmugen.linux 2014-06-15 14:48:04 UTC
I wasn't sure if I should've just edited my previous bug post #72819 since the problem persists with a newer version of MESA.  But as the subject heading reads, that's exactly what happens.

I was testing Linux Mint 17 Cinnamon edition with the same video hardware (Intel 82852/855GM) and I noticed some things compared to the previous Linux Mint 16 Cinnamon edition:

1)  In Cinnamon for Linux Mint 16, the background color for all drop-down menus wasn't visible, making it very difficult to read the text for each menu item.  In Cinnamon for Linux Mint 17, the bug appears to be fixed; the background color is now visible.

2)  However, for Cinnamon under Linux Mint 16 and 17, regardless of what alternate appearance theme I tried to apply, the windows always show the incorrect dropshadow color (white) instead of black.

The terminal outputs for glxinfo (when I'm testing under Linux Mint 17) show that I am indeed running MESA 10.1 and that I do have direct rendering enabled.

While I have absolutely NO idea what's causing this or what packages are responsible for whatever else, the following list are of packages that I'm currently using, that I think have something to do with this bug, and their current version numbers:
*libdrm-intel1 v2.4.52-1
*xserver-xorg-video-intel v2:2.99.910-0ubuntu1
*libgl1-mesa-dri v10.1.0.4.ubuntu5
*libgl1-mesa-glx v10.1.0.4.ubuntu5
*libglapi-mesa v10.1.0.4.ubuntu5
*libglu1-mesa v9.0.0-2
*linux-kernel-generic v3.13.0-24
*linux-firmware v1.127

Please note that I'm experiencing this bug on Linux Mint 17 Cinnamon Edition with the Intel 82852/855GM chipset.

Presuming the shadows are fixed by:
