bug#28536: 26.0.60; cannot set frame geometry, plus weirdness

[Nick Helm]

Emacs does not set frame geometry parameters correctly:

  Emacs -Q

  (frame-parameter nil 'width)  -> 75
  (frame-parameter nil 'height) -> 35
  ;this is already odd as default geometry should be 80x36

  (set-frame-parameter nil 'width 105)

  (frame-parameter nil 'width)  -> 100 ;width is incorrect
  (frame-parameter nil 'height) -> 35

Setting frame width also seems to somehow influence frame height:

  (set-frame-parameter nil 'width 105)
  (set-frame-parameter nil 'width 105) 
  ;set frame width a few more times
  ;the frame pixel height changes by a fraction of a char each time

  (frame-parameter nil 'width)  -> 100
  (frame-parameter nil 'height) -> 34  ;height changed

Apologies all, this was my fault. I misunderstood the discussion in an
old bug report that probably should have been closed as notabug.

I’ve reverted the change now.

Thanks for your reports.

Thanks Alan, it's all working as expected again.
