Description:

I have two external monitors connected to my laptop via a dock. When I switch between the two monitors in my window manager, the previously focused monitor flickers (bottom half black).

Also, the output intermittently flickers even without switching focus.

journalctl reports errors in i915:

Feb 11 11:56:16 ganymede kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun
Feb 11 11:56:16 ganymede kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun

Similar problem here: two external monitors connected to laptop via mini display port. When i switch focus, sometimes (not all the time) the previously monitor goes completely black and turns on again after 1-2 second.

Can't see errors in journalctl though.

I cannot reproduce the bug.

Is this issue still valid?
