pdf windows scrolled to top of current page

[Fritzkefit]

Whenever I call 'ace-window' with more than 2 windows, i.e., whenever the ace-window keys are displayed, it scrolls to the top of all windows displaying pdfs (it doesn't matter whether I use DocView or pdf-tools). When switching with 'other-window' this does not happen.
Unfortunately this is very annoying; for instance, when you try to translate mathematical formulas --on which I zoomed in, in the middle/bottom of the pdf page-- into code opened in another window.

This happens for me also. It seems like it resets the pdf-view window when ace-window tries to draw the selecting character, which it fails to do. Can I tell ace-window to not draw on pdf-view windows?

I noticed now that ace-window doesn't fail to draw the selecting character, but it draws it halfway down the PDF page, not in the top-left as is the case for all other windows.

I was noticing the same (scrolling to top of pdf, drawing the character halfway down, on the left).

The posframe versions of either #204 or #192 do not show these issues.
