Description of problem:
When using emacs on a HiDPI screen, when opening a file, the window will take up the entire screen width.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open emacs on a HiDPI screen
Window takes up the entire screen
Window is a standard 80 column width
I have a hand-crafted X environment on a HiDPI display where I have the X
server DPI set accurately (in various places) and normally set GDK_SCALE=2
and GDK_DPI_SCALE=0.5. Un-setting both environment variables caused Emacs
to stop doing this maximization at startup, as does setting both of them to 1.
I'm using emacs-25.3-3.fc27.x86_64.
This maximization appears to override all other ways of setting Emacs'
initial size. I have X resources set, I have used -geometry on the
command line, and I have tried setting initial-frame-alist and so on in
my .emacs. None of them had any effect. Nor did starting Emacs with '-q
This appears to have been fixed in emacs 26.1, which is now in F28. :)
