            Bug ID: 97022
           Summary: Garbage in windows while running a game windowed
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

Photograph of screen when the problem occurs

This is an odd one, as of posting I have only managed to reproduce this when
using a Virtual Programming OpenGL 3.2 based game, such as The Witcher 2. I
have not been able to reproduce it with Valve's Source games.

For example, If you run The Witcher 2 in windowed mode, and allow it to get to
the menu screen, doing anything with another window (such as resizing) causes
the display to turn to junk. Eventually the whole X11 display will be corrupt,
and only rebooting the system will clear it. Text mode TTY's are unaffected.

Occasionally, rather than corruption, the system will lock up, requiring a hard
reset or magic sysrq reset. I could not find a way to consistently reproduce
this though, whereas I can consistently reproduce the corruption.

Specs:
Xubuntu 16.04.1 LTS
Kernel 4.0.0-31-generic, x86_64
Mesa 12.1.0-devel (Padoka PPA)
DRM 2.43.0
GPU Radeon HD 7750 (CAPE VERDE PCI 1002:683F), 1GB VRAM
Xorg 1.18.3
Desktop Xfce4 4.12, using builtin compositor

Disabling the compositor makes no difference. Restarting Xorg when the fault
occurs makes no difference.

The bug is not present in the 11.2.0 release of Mesa shipped with Ubuntu 16.04
by default.

So far I have only produced this bug with two of our games - The Witcher 2, and
Overlord (due to be released today).

Witcher 2 causes the display corruption seen in the screenshot. Overlord
produces corruption quickly followed by a system lockup. Alt-SysRq-B rebooted
the system, and I have attached the last written messages to kern.log

Can you bisect Mesa? Note that Xorg needs to be restarted before testing each
commit, as glamor might contribute to the problem.

Not easily as I am not currently compiling Mesa, but rather using the version
built by the Padoka PPA in Ubuntu

Today I gave the latest Padoka (git1600721124400.4f89cf4) a try during
debugging Overlord. I got a screen corruption followed by a hang.

Just as I was about to reach for the SysRq keys, Xorg restarted, and seemed to
operate as normal - except I was now on llvmpipe instead. Quite an amount of
kernel log was generated, and some relevant looking info in Xorg.log too. They
are attached here.

Part of kern.log written during forcing a GPU reset

I've found that force resetting the GPU clears the corruption - using cat
/sys/kernel/debug/dri/0/radeon_gpu_reset

This does not take effect straight away however, I often have to kill Xorg
before it'll happen. There are some errors written to the kernel log - i have
attached those.

Here is lspci output for the card in case it's relevant:

Confirmed.

ArchLinux: 4.6.4 x86_64
Mesa: 12.0.1
GPU: AMD Curacao PRO [Radeon R7 370 / R9 270/370 OEM]
Xorg: 1.18.4

Game: Overlord

What makes you think it's a regression in Mesa?

--- Comment #10 from Peter Mulholland <peter.mulholland@vpltd.com> ---
I am not sure exactly what this comment means, so I will answer as thoroughly
as I can.

I am not 100% sure that "mesa" is the component responsible, it could be drm or
radeonsi. I am not familiar enough with the Mesa components to be sure.

The problem described does not happen with the Mesa 11.2.0 distribution that
Ubuntu Xenial has packaged by default. The problem only occurs when Mesa 12.1.0
is installed using a PPA such as Oibaf or Padoka.

It also does not occur on Mesa 12.0.1 that is part of an installation of
Manjaro (Arch Linux) that I have on the same machine.

The problem does not occur with the nvidia or fglrx binary drivers.

The problem is not just an app crash, but display corruption/kernel panic. This
should not happen due to the behaviour of a userspace app, even if our apps
were doing something "wrong", being able to crash the whole machine is a bug.

No, I was asking Michael actually, but thanks for explanation, it guves a clue.

Regression is a situation when something was working before update and stopped
afterwards. So in your case in Mesa 11 it worked and broke in Mesa 12. Most
likely something was broken between releases, that's why Michael asked for
bisect.
