i've made 3 recordings of strange new behaviour of pager_plain and switching between virtual desktops with XVidCap (watch with ImageMagicks animate). they are in this github repo. it's very confusing and hard to describe...
a) i have tiling set on virtual desktops 2-4. when i open a program in one of these (eg. terminal) it's obviously maximized. when i switch to another virtual desktop and then back sometimes they are not fullscreen anymore, but a little bit shorter. (screenshot, look at the terminal. hint: left and right screens are 1280x1024, center is 1920x1080). this could be another issue with focus, too, as then they haven’t got their focus back and won't get it back unless i resize the window with my mouse binding (see below). also their content is not drawn while this happens (eg top just hangs).
b) [switchbetweenvirtualdesktops.tar.xz]: i don't know if it's related or not, but when changing virtual desktops some icons in the pager_plain "jump" (regardless if i switched from that virtual desktop or to it).
c) [opensettings.tar.xz]: icons also "jump" in the pager_plain when i open or close settings. maybe these windows get resized for whatever reason and the pager reacts? this would fit with d).
d) when switching back to a virtual desktop, a maximized window, here nautilus, is resized and repositioned to the full length of the screen (screenshot) and under my shelve. interestingly immediately after i pressed the print key the window was again resized and reposition to it's original position just right of the shelve. however, at random, it might also be resized to be greater on the right side and immediately back to the size of the screen. watch the right side of the recording! (see [switching-resizes-gnome-nautilus.tar.xz] - this is bigger then 1920x1080!)
i hope i made some sense somehow.
Mouse Binding: Left button + WIN = Maximize Mode "Smart"
Window Geometry -> Maximization -> "Allow manipulation of maximized windows"
