When running
/usr/bin/emacsclient --eval '(make-frame)'
it sometimes (often) opens up a small window (10x21) instead of the expected 40x80 window.
Setting a hook for after-make-frame-functions like this:
(progn
(setq after-make-frame-functions nil)
(add-hook
'after-make-frame-functions
(lambda (frame)
(let ((width 80)
(height 40)
(start-width (frame-width frame))
(start-height (frame-height frame))
(visible (frame-visible-p frame)))
(print (format "Start %dx%d %S"
start-height start-width visible))
(if (not visible)
(progn
(while
(not (frame-visible-p frame))
(progn
(sleep-for 0.001)
(print (format "X %dx%d"
(frame-height frame)
(frame-width frame)))
))
(sleep-for 0.001)
(print (format "Resetting %dx%d -> %dx%d"
(frame-height frame) (frame-width frame)
height width))
(set-frame-width frame width)
(set-frame-height frame height)
(sleep-for 0.1)
(print (format "Resetting %dx%d -> %dx%d"
(frame-height frame) (frame-width frame)
height width))
(set-frame-width frame width)
(set-frame-height frame height)
)
)
)
(print (format "Done %dx%d"
(frame-height frame)
(frame-width frame)))
)
)
)
usually has two different outcomes:
"Start 10x38 t"
"Done 10x38"
or
"Start 40x80 nil"
"X 40x80"
"X 40x80"
"X 40x80"
"X 10x21"
"Resetting 10x21 -> 40x80"
"Resetting 40x80 -> 40x80"
"Done 40x80"

Isn't this because we wait fro X to resize the frame after we ask for
it?
