           Summary: [bisected] Wrong display after "prefer native texture
                    formats when possible" commit - part2
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: palatis at gmail.com


After I update to the latest mesa git
(85e1fa55066783d2748993810708dee6db7a4993) I found out the some programs
(`cairo-dock -o` and gnome-terminal) start not to paint itself.

After some time bisecting, I found the commit which caused the problem is
1a339b6c71ebab6e1a64f05b2e133022d3bbcd15.

A google search #38602 and #38610 indicates
1f544cc58794cffe5d5cac5a83efde91154f1b7d fixes this, but not my case.

Everything was good with 98ce1373e47d05d7150933c391fdeddbc897a3cd.
With 1a339b6c71ebab6e1a64f05b2e133022d3bbcd15, X goes to CPU 100% after
cairo-dock started.
With 1f544cc58794cffe5d5cac5a83efde91154f1b7d, X starts to work again, but
cairo-dock is not rendering anything (click on the "invisible" icon brings up
program, though), and gnome-terminal doesn't render anything in its console
part (see attachment).
Going all the way to the latest commit
(85e1fa55066783d2748993810708dee6db7a4993) does not help.

I'm on a ATI Mobility Radeon HD 4530 512MB with git-sources-3.0-rc7:
# lspci -nn | grep VGA
02:00.0 VGA compatible controller [0300]: ATI Technologies Inc M92 [Mobility
Radeon HD 4500/5100 Series] [1002:9553]
# uname -r
3.0.0-rc7-palatis

xorg-server is 1.10.3 (as shown in `X -version`).
libdrm is at commit 8d055890d90c3d92647e3d8b98d32630ef87c2c8.
xf86-video-ati is at commit e8d0d437957b15252dfad775796a3949ed50dbcf.

However, another computer with a HD 3300 doesn't have the problem, everything
was great with this card:
# lspci -nn | grep VGA
01:05.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon HD 3300
Graphics [1002:9614]
