Running Ubuntu 18.04.1 LTS with X and GNOME.

I have (mainly) 2x monitors. One 22" and one 24". The 24" is the main monitor. I activate the 22" when needed. I have the extra monitor on the left hand side. Main is HDMI and extra is DVI-D.

Issue is that programs like Firefox seem to get some glitches when sized over 22" on the 24". Most visible is Theme that does not "expand" to fit the window. The close ×'s also get unaligned and obscured from time to time. (Hard to cross out.) Especially on the "above 22inch section".

Firefox on 24" at width of 22":

Firefox on 24" at width of 24". The gray area should be of theme:
