Description adam winberg 2015-03-23 07:16:40 UTC
Description of problem:
After upgrading to 7.1, tearing started to appear when our HP laptops/desktops with Intel i915 driver are connected to external monitors. It does not always show, but most of the time, specially when toggling the notification area (Super+M) or starting the Activities screen (Super). Using the laptop screen as a third monitor seems to make the problem worse.


Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.99.916-5.el7.x86_64

How reproducible:
Intermittently

Steps to Reproduce:
1. Use two external monitors
2. Toggle notification area
3.

Actual results:
Screen flickering and tearing

Expected results:
No tearing.

Additional info:

Creating an xorg config with 'TearFree' option, like this:
/etc/X11/xorg.conf.d/20-intel.conf:
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
   Option      "TearFree" "true"
EndSection

solves the problem. Should not be needed though.

Adam,

we wasn't able to reproduce but would you be able to test the fixed package once available?

Thanks

Many users are facing this issues with Intel graphics card c=screen tearing. I was facing this after updating an Ubuntu 15.10, however reverting some information at https://www.hpsupporthelpline.com/ it was solved.

After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
