I was not able to reproduce the issue.
I used the latest master of virglrenderer and mesa on an Intel Kabylake
host, and disabled the copy_image copy path via
so that virglrenderer could not use this shortcut for copy-blits.
Inside the guest I used Ubuntu bionic with the latest updates and a PPA
kernel: Linux version 4.16.0-041600-generic (kernel at kathleen)
(4.16 is needed to support report host caps v2 to the guest).
I tried both blackbox and a gnome-session with chromium-browser and I
didn't seen any of these artifacts. What is actually the desktop
environment that you were using?
