[Bug 1307144] Re: 'unredirect fullscreen windows' causes tearing

 

I had to switch permanently to Intel GPU. Nvidia driver makes the system
unusable for daily use. Such a shame.

Sadly, Ubuntu 12.04 (in early phase using Bumblebee) was smooth. With
each Ubuntu upgrade my problems gets bigger and bigger using the same HW
base.

Maybe time to improve testing & acceptance procedures before major
releases  ??

Title:
  'unredirect fullscreen windows' causes tearing

Status in “compiz” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu release: 14.04
  Installed compiz version: 1:0.9.11+14.04.20140409-0ubuntu1

  The option 'unredirect fullscreen windows', which is enabled by
  default in Compiz, causes tearing in games and other fullscreen OpenGL
  applications, even with 'sync to vblank' options enabled in ccsm, in
  the GPU settings and in the game.

  With this option disabled, VSync works as fine as should with
  'unredirected fullscreen windows' enabled and there is no tearing (but
  this causes performance issues and the Unity panel shadow on top of
  the application).

  Tested with:
  - ASUS NVIDIA GTX 650-E-1GD5 with NVIDIA proprietary driver 331.38 (tested) (nvidia-331)
  - the same graphics card with NVIDIA proprietary driver 331.38 (nvidia-331-updates)
  - the same graphics card with Nouveau open source driver (xserver-xorg-video-nouveau)
  - Intel HD 4000 iGPU with default open source drivers
