Example of artifacts

Hello,

I want to report some graphical artifacts with AMD Radeon RX 570 card.

I've been noticing some random artifacts when I open/resize/close windows.
I was able to narrow down this problem to mesa surfaces updating. For instance
if i suspend program with such surface and try to resize it, I will see these
artifacts. So I think there is a moment between receiving resize event and
updating surface when driver somehow render those artifacts.

I'm using Arch Linux with i3, but I was able to reproduce this bug on wayland
by resizing alacritty terminal emulator.
