Interesting the workaround would not work, because it looks like bypass mode has the wrong pixel format. But I'm also glad bypass isn't broken too. Please double-check that the workaround really does not help. Also remember to reboot.

Secondly, please try this (or something like it):
  1. sudo apt-get install mir-demos
  2. Reproduce the corruption
  3. Switch to a VT that works (Ctrl+Alt+F1) or install openssh-server and ssh in.
  4. sudo mir_demo_client_egltriangle
  5. Switch back to VT 7: Ctrl+Alt+F7
Now, is the triangle visible without corruption? Can you take another photo?

If all else fails, are you able to look in your /var/cache/apt/archives/ and find which package version introduced the bug, by installing slightly older versions? You can just:
    cd /var/cache/apt/archives/
    sudo dpkg -i <whatever deb files to try>
