Commit 91c42093b248 ("glx: Duplicate relevant fbconfigs for compositing visuals") adds many new depth 32 fbconfigs as composite visuals. On a X-Screen running at depth 24, this also adds bgra 10-10-10-2 fbconigs, as they also have config.rgbBits == 32, but these are not displayable on a depth 24 screen, leading to visually corrupted desktops under some compositors, e.g., fdo bug 104597 "Compton weird colors" when running compton with "compton --backend glx".
Be more conservative for now and only select fbconfigs with 8 bpc red, green, blue components for composite visuals.
