Half-screening Firefox sometimes scrambles the window
This is the first time I have seen this problem.
Dragging Firefox to fill the left half of my left screen of my dual screen setup scrambled the window contents and window top bar. I could then move it around to the position in the picture below. After dragging it full screen again, all was fine. This didn't repeat itself. Note that the orange wood-like pattern is added by me.
Arch Linux, linux 4.16.9-1, vulkan-intel 18.0.3-4, xf86-video-intel 1:2.99.917+831+ge7bfc906-1
