Would it be possible to change something in the theme xml files to cause 
the popup to display differently? Say anchor it to 0,0 so that the 
scaling error does not cause the clear space to the left to push the 
message off the screen to the right? Just as a work around until the 
problem is fixed. Since it does not seem to affect many people I imagine 
the priority is not particularly high.

If this can in fact be done how would one figure out which element of 
the xml files is being used for the message popup?
