[regression] Restoring a maximized Gnome Terminal window with keybinding fails to restore the original geometry

[Sami Jaktholm]

Steps to reproduce:
1. Open Gnome Terminal
2. Maximize the window with the maximize keybinding (Ctrl+Super+Up)
3. Immidiately restore the window with the restore window keybinding (Ctrl+Super+Down)

What happens:
- Window is unmaximized but it still fills the entire desktop

What should happen:
- Window returns to the exact size it had before maximation.

Testing this with Metacity and Mutter shows that this is compiz related (no problems there). It seems that Compiz properly restores the window but gnome-terminal immediately resizes the window back to it's maximized size. Gnome-terminal seems to react to focus in/out events by recalculating its size. When compiz restores the window, GTK apparently gives terminal the old size instead of the new one (maybe a syncing issue between compiz/X/gtk?)

Also present in the r3569 of compiz trunk.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Another way to reproduce this: (taken from bug 1138489)

To reproduce (both in currently released and trunk Unity):

 1. Open gnome-terminal
 2. Drag the terminal up to the panel to maximize
 3. Drag the terminal down to unmaximize (or click the unmaximize button). Observe the window maintains maximized proportions

Interestingly, if you switch focus to another application after step 2, the terminal *will* restore correctly.

This is a very annoying bug for me. I wish it were fixed in Raring but it's not.

[Ben Gamari (bgamari)]

Does a fix for this bug currently exist in unreleased form somewhere? This is really breaking my workflow.

[David Perkinson (davidp-reed)]

I've got the same problem with

Linux 3.8.0-22-generic #33-Ubuntu SMP Thu May 16 15:17:14 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I fix would be *much* appreciated. Does anyone know of a temporary workaround?

Still present in Saucy.

Just noticed that `gtk_window_set_geometry_hints` and `GdkGeometry.base_width` and `GdkGeometry.base_height` are related to another bug, and quite possibly related to this one too.

In this bug, if I add a VteTerminal widget to a GtkWindow and use GtkWindow.set_geometry_hints as per the example on the Devhelp documentation, the result is that if I repeatedly press Ctrl+Super+Up then Ctrl+Super+Down (or maximized/restore via title bar dragging) the window size will slowly decrease to its minimum (this actually happens with xfce4-terminal).

Now if I set the GdkGeometry base size to, say, 80x24, the window size will decrease/increase automatically (via the sequence of maximize/restore) iff the current unmaximized size is different than the base size (that is, the window tries to restore to the base size of the geometry hint).

Don't know if this bug has being reported, but I think is related and a possible solution could imply updating the window base size to the size before maximization, so this "restoring" effect wouldn't be perceptible. Of course, this would be just a workaround since compiz looks like the main suspect, here.

The file in gnome-terminal is `src/terminal-window.c` and I think it would be needed to modify `terminal_window_update_geometry` and `terminal_window_set_size_force_grid` (in the latter is the misbehaving code, in the former is the gtk_window_set_geometry_hints stuff).

[Martin Kaistra (djfun)]

cannot reproduce this in trusty anymore

[Matthew Eaton (powder)]

Fixed in Trusty for me as well.

[le_jawa (le-jawa-gmail)]

I'm experiencing this in Trusty. I thought it had been fixed a while back, but evidently not. My system has a multi-monitor configuration, which may affect this. Screenshot attached.

This bug is quite old and we didn't manage to reproduce it, therefore I marked it as invalid. If you still experience the problem please feel free to re-open it and update the description! Thank you!
