I attached a screenshot. I don't think the problem is Ubuntu MATE specific. I also found it doesn't depend on the display manager. (It can be either LightDM or GDM.) Reproduce instructions: 1. Boot up a KVM virtual machine with an Ubuntu Vivid Vervet image. 2. Put some stress on the display: what I used to do is to launch Firefox and htop in a terminal, then lock the screen, or let it lock by itself. 3. Wait a little, then unlock the computer. 4. You'll see letters missing and images corrupted, like on the attached screenshot.
