Description almos 2014-04-27 18:50:54 UTC

Enemy Territory Quake Wars saves 32 bit TGA screenshots, and the alpha value of the pixels is set to 0x00 instead of 0xFF. Team Fortress 2 saves 24 bit TGA screenshots (before converting to jpeg), and the whole thing is black.

I also tried Doom3, Prey, Quakespasm, Nexuiz, UT2004, Half-Life 1, and Garry's Mod but those are not affected.

This is a regression, but I couldn't find an old version of mesa that worked. I went back as far as to 5ffa28df4e4cc224 (the first one that compiles with bison 3), and libdrm 2.4.44, but couldn't find a version that was good. When screenshots were good, I had mesa 9.2.2 installed, and I used 10.0-dev for running games. Now I have 10.1 installed. Maybe I need to roll back the installed libs?

Possibly a duplicate of bug 77553.  See also:

Bug 77553 mentions commit 234db609544ee521458ce8b648e70cffe2fda6f9 as the culprit, but my git checkout is definitely earlier than that, and mesa 10.1.0-5 in Debian Sid shouldn't contain it, either.

Now TF2 screenshots are good. I didn't change anything on my system, maybe it was a TF2 issue, and it was fixed by Valve. ETQW is still wrong.

Comment 5 Benjamin Bellec 2014-09-02 16:15:04 UTC

I don't think this is a Mesa bug.
I already noted this problem with ETQW back to July 2012 (maybe even earlier) and found a workaround. You can convert the picture to PNG thanks to ImageMagick, just run :
$ convert -alpha off shot00016.tga shot00016.png

With my RV770, I just tested mesa-10.3-rc2, mesa-9.2.5 and mesa-9.1.7. All of them gives bad TGA screenshots.

Comment 6 almos 2014-12-06 13:44:03 UTC

Some update on this: in TF2 only the first screenshot is black, but subsequent ones are good.
