Bad icons in Steam Big Picture mode
During testing of SteamOS, we would sometimes see incorrect icon colors in
Steam Big Picture mode.
I was able to capture the behavior in a trace. I've attached a screenshot of
the issue. I've got a 137MB apitrace file of it, if anyone is interested.
We bisected it to 61e264f4, which changes the internal format of textures,
routing glTexImage2D to new code paths.
We debugged it to PBO offsets that are not naturally pixel aligned, which
causes the BLT path to drop bits.
I've got a fix to send to the list, and will also submit a piglit test that
shows the issue.
I'll update this bug as I send out the patches and tests.
