1435159 - Window does not fill full size on tiling wm

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect, P5)

Description

[ibrokemypie]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180127220259

Steps to reproduce:

Close firefox with hotkey
Open firefox with hotkey


Actual results:

The browser opens but only properly updates a portion of the window, the rest is broken and stays the same until something draws over the area, such as switching workspace, then it becomes blank, or resizing the firefox window, which fixes the issue.


Expected results:

Firefox should open and displa correctly fro the entire window size

Any ideas, :jrmuizel?

Since this depends on the window manager it is probably some weird interaction with Widget. I'm moving it there.

I suspect this will need someone to actually debug what Firefox thinks is happening with the window size.

ibrokemypie, is this a regresssion? Did older versions work?

I have a similar behavior with sway.

Through playing around with opening and closing firefox in different situations
I think I know what went wrong (through not how/why it did).

Basically it seems that when firefox is opened it assumes to have the same
space for rendering the page as when it was closed. Or at last it does something
in that direction.

For example if I close a full-width/high firefox and then
open it in a context where it will only get a half height
window it will have a part of the webpage "outside" of the
screen so if I scroll down I will not see the bottom of the
page.

If I close a fill-width/hight firefox and then open it in a context with a half width
it will render the screen and setup the scrolling as if it would have twice the width.

If I close a half-width, half-hight firefox and then open it in context where it will
get full width + hight it will only render in the upper left quarter of the space 
available for rendering the website. (through the UI elements are rendered in full size
same as in the screenshot).

Through I noticed that resizing firefox once will make it behave again (at last in
my setup). So it seems to be some conflict of firefox wanting to open itself with the
size it was closed and assuming it actually was opened with that size.
