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