OpenBSD desktop dimensions and mouse offset issues

OpenBSD works great with a few annoyances.

  1. The VM mouse pointer (openbsd) is always somewhere that is not where the host (qubes) mouse pointer is.
  2. The window max size is limited. I have found some configs for this, it did make the window bigger but the desktop did not seem to catch on, blocking the mouse and apps from using it.
  3. The desktop is larger than the host window, enough to block taskbar icons in things like xfce.

This is in reference to openbsd 7.5 and earlier.

Any help appreciated!
