Description

Same issue here on both KDE Plasma (X11) and Gnome (Wayland) sessions. Hardware is a Intel 1st Gen Core processor. kernel-4.4.3-300.fc23.x86_64 and kernel-4.4.2-300.fc23.x86_64 xorg-x11-drv-intel-2.99.917-19.20151206.fc23.x86_64 Note that these flashes behave like the F22 wayland freeze exception bug #1218688: The screen flashes black on all lines below mouse cursor for a short time (probably one single frame). Flicker only happens while moving the mouse, not triggered by anything else. This time it isn't happening all the time but no matter whether I use X11 or Wayland. Additional info: kernel-4.3.5-300.fc23.x86_64 is not affected. I'm seeing bug #1312610 and #1312678. And a similiar error in syslog as noted above: kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun Furthermore I'm getting those error messages: gnome-shell-wayland.desktop[3359]: (EE) glamor0: GL error: FS SIMD8 shader: 302 inst, 0 loops, 4232 cycles, 0:0 spills:fills, Promoted 0 constants, compacted 4832 to 4240 bytes. gnome-shell-wayland.desktop[3359]: (EE) glamor0: GL error: FS SIMD16 shader: 304 inst, 0 loops, 4630 cycles, 0:0 spills:fills, Promoted 0 constants, compacted 4864 to 4272 bytes. gnome-shell-wayland.desktop[3359]: (EE) glamor0: GL error: FS SIMD8 shader: 274 inst, 0 loops, 3830 cycles, 0:0 spills:fills, Promoted 0 constants, compacted 4384 to 3824 bytes. gnome-shell-wayland.desktop[3359]: (EE) glamor0: GL error: FS SIMD16 shader: 276 inst, 0 loops, 4180 cycles, 0:0 spills:fills, Promoted 0 constants, compacted 4416 to 3856 bytes. gnome-shell-wayland.desktop[3359]: (EE) glamor0: GL error: VS vec4 shader: 8 inst, 0 loops, 190 cycles, compacted 128 to 128 bytes. maybe same as bug 1310252. There was a potential flickering fix but I didn't pick it up because I saw a report it didn't fix anything. If you'd like to give it a test to really confirm, please try http://koji.fedoraproject.org/koji/taskinfo?taskID=13191219 when it finishes.

Before applying (with 4.4.2 and "stock" 4.4.3 kernels) I could reliably reproduce flicker when dragging the map on http://flood.firetree.net . Now I can't reproduce the flicker any more. The first set of error messages from description any comment #1 seems to be gone, the second set of errors from comment #2 is still present and so probably unrelated. Thanks for testing. I'm going to bring the patch into F23. It should show up in the build for 4.4.4 which should show up in testing on Thursday or Friday Confirm that 4.4.3-300.rhbz1313318.fc23.x86_64 fixes it. Thanks!
