Description rkmugen.linux 2013-12-18 04:12:05 UTC
Hello, I have an 82852/855GM graphics chipset and I'm using Linux Mint 13.

I'm encountering two annoying problems:  The first is when I try to use the Cinnamon-3d desktop environment, and the second problem involves GLX-dock.

Incorrect (white color) drop shadows drawn underneath windows.  I have detailed this problem, as well as my system hardware/kernel/driver specifications, as best as I could in the Linux Mint forum below.  I have also provided a few screenshots in that thread.:
    *http://forums.linuxmint.com/viewtopic.php?f=208&t=136419

A strange white rectangle, the size of the entire dock appears whenever I show/hide the GLX-dock (using the OpenGL backend).  For this problem, I've uploaded a short YouTube video to show exactly what I'm talking about as it happened.:

I should point out that whenever I show or hide the GLX-dock, I get this terminal output:

------
warning :  (build/buildd/cairo-dock-3.3.99.alpha1.1-20131204~bzr1685/src/implementations/cairo-dock-hiding-effect.c:_pre_render_opengl:53)
  FBO not ready
------

I know/believe the 82852/855GM chipset is at least more than capable of handling something as simple as a dock and drop shadows.  Is there anything I can do

[PATCH] cairo-dock: Fix white flash when NPOT textures aren't available

The white flash looks to be a bug in cairo-dock. This patch fixes it for me, although it's possible some other rendering error will remain since the texture coordinates might no longer be entirely correct since the actual image no longer fills the entire texture.

I'm too lazy to register to launchpad so that I could report the bug to cairo-dock. But feel free to forward this patch to cairo-dock developers.

The white flash is not a Mesa issue so I'm closing this bug.
