            Bug ID: 105273
           Summary: [r350] missing background, transparency not working &
                    other glitches in ETR (AGP, ppc, mesa-18.0.0_rc4)
           Product: Mesa
           Version: git
          Hardware: PowerPC
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300

ETR on ppc, pic 0

I know, I know - yet another bug of something not working on ppc. But actually
things have improved in the meantime. Since a complete system & kernel rebuild
with gcc 7.3.0 my AGP Radeon 9650 and 9800 started working decently (see bug
#105254). And mesa 18.0.0_rc4 certainly shows less glitches than 17.2.x and the
versions before. Colors are right and Extreme Tux Racer runs smoothly.

What's not working is transparency and the background is missing too. Another
thing is this strange misplacement of trees and the start/finish banner on the
track (lying on the side instead of standing).

I'll add pictures, you will notice immediately what I mean.

Just tried software rendering for comparison. Using softpipe ETR runs like on
amd64 without any glitches. Albeith unuseable slow on a G5.

Tried a Radeon HD 6450 on my PCIe PowerMac G5 11,2 for another comparison.
Graphics are rendered correctly! So it seems this bug is a specific r300 driver
problem, not a generic Big Endian problem.
