  Corruption is seen on windowed 3D apps running on dGPU

  [Test case]

  Get a certain Intel/AMD hybrid machine, run 'DRI_PRIME=1 glxgears',
  see how the window has corrupted gfx.

  The fix is to patch Intel i965_dri driver.

  [Regression potential]

  There could be a slight loss of performance, but corruption free
  behaviour.

[Timo Aaltonen]

Hello Timo, or anyone else affected,

Accepted mesa into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/mesa/17.2.4-0ubuntu1~16.04.4 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Taihsiang Ho]

Hi, I can't reproduce this issue with a fresh installed Artful on the I+A 
system[1] with gfx
  - Intel Corporation HD Graphics 520 [8086:1916] (rev 07)
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / 
M340/M360 / M440/M445] [1002:6900] (rev 81)


I might need more information to reproduce and make sure this issue on Artful 
as well.

  Corruption is seen on windowed 3D apps running on dGPU

  [Test case]

  Get a certain Intel/AMD hybrid machine, run 'DRI_PRIME=1 glxgears',
  see how the window has corrupted gfx.

  The fix is to patch Intel i965_dri driver.

  [Regression potential]

  There could be a slight loss of performance, but corruption free
  behaviour.

[Timo Aaltonen]

This patch broke the DRI driver on older gen4/4.5/5 Intel HW, see bugs
1735594 and 1741447

I've backported five commits from upstream to fix this properly, at
least this backport doesn't crash on my HW anymore.

  Corruption is seen on windowed 3D apps running on dGPU

  [Test case]

  Get a certain Intel/AMD hybrid machine, run 'DRI_PRIME=1 glxgears',
  see how the window has corrupted gfx.

  The fix is to patch Intel i965_dri driver.

  [Regression potential]

  There could be a slight loss of performance, but corruption free
  behaviour.

Hello Timo, or anyone else affected,

Accepted mesa into artful-proposed. The package will build now and be
available at

few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, details of your
testing will help us make a better decision.
