I do use a workaround, and that does remind me of some issues I had with 
mismatched resolutions:
    - I get 2 cashews on the widest display (in pixels).
    - Maximized windows occupy space beyond the right and bottom edges of
        the smaller screens (in pixels).

Anyhow, what you want to do for now, is apply to all monitors the same size in 
pixels.

Get a list of screen sizes that work for your monitors.  Choose among 
resolutions that have the same size in pixels for each monitor.

For my monitors, the common denominator is:  1280x1024

So, you go into:  /etc/X11/xorg.conf

Duplicate each of the "Modes" lines in the "Display" subsections of 
the "Screen" sections.  Comment out one of each of the lines.

Use your common denominator size as the first listed (and largest) resolution 
(if you include any other resolutions at all).

Restart your X server.

That should do it, until someone fixes the issue.  At that time, you delete or 
comment out the "Modes" lines that were used as the workaround.  And, you 
need to uncomment the "Modes" lines that you originally had.
