--- Comment #3 from achat1...@free.fr --- An update on this. I update my Neon to hwe stack 16.04 (linux kernel 4.8 + xserver) and problem seem gone on the Skylake config and greatly improve on the Ivy Bridge (can still see a little flickering on the edge on panel when closed but the whole panel stopped flickering) (packages I installed are: linux-generic-hwe-16.04 and xserver-xorg-hwe-16.04) -- You are receiving this mail because: You are watching all bug changes.
