Hello, First of all I love the new GNOME 3.16 release. The notifications and system tray icons (in the left) are great and productivity boosters. However, I'm having some issues with Intel HD graphics on X11 that make things very difficult. Though these problems are solved by the Wayland session it's still too unstable for me to use in production as a day-to-day desktop. Hardware: Intel® Core™ i5-4200M CPU @ 2.50GHz × 4 Intel® Haswell Mobile (HD 4600, i965) GNOME: Version 3.16.2 Kernel: 4.0.4-301.fc22.x86_64 Problem: [1]https://bugzilla.gnome.org/show_bug.cgi?id=741376 At work I use two external monitors in addition to the laptop screen. VSYNC often breaks when using either SNA or UXA at random intervals. It also breaks also when I fullscreen any application in any monitor. Even when I force VSYNC in both xorg.conf and drirc it doesn't seem to help. These are configurations for reference: /etc/environment: CLUTTER_VBLANK=True /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" Option "TearFree" "true" Option "SwapbuffersWait" "true"
Try Option "DRI" "2" in conjunction to the above.
We no longer default to DRI3 in F22.
