Public bug reported:

Binary package hint: xorg

When changing resolution from 1024x764 -> 800x600 with the VESA driver,
the screen becomes garbled (including the cursor).

Steps to reproduce:
1) Make an xorg.conf using the VESA driver. (I modified the one generated by Xorg -configure to do this.)
2) Reboot with parameter radeon.modeset=0 to allow VESA driver to load.
3) Login.
4) Open System -> Preferences -> Monitors, change resolution to 800x600.
5) Click Apply.
6) Screen becomes garbled, including cursor.
7) Press ESC to cancel the resolution change and switch back to 1024x768, after which everything is fine.

This is probably a dupe of bug 138087, but I was instructed there to
file a new report.
