Making width to 100% moves terminal to center of screen with xfwm4

[amab8901]

Expected Behavior

If the terminal is positioned at the top, and I set the width to 100%, then the terminal should remain on the top of the screen.

Current Behavior

If the terminal is positioned at the top, and I set the width to 100%, then the terminal gets moved to center of screen.

Possible Solution

Steps to Reproduce (for bugs)

Here is initial state:

Appearance:

Behavior:

Shortcuts:

Dropdown:

Bookmarks:

Now, to trigger the bug, do the following: Preferences > Dropdown > [Width = 100%]

Context

It's annoying that I have to choose between having a gap on the sides and a gap on the top. Why can't the terminal just meet the edge both on the top and the sides simultaneously?

Not reproducible here.

Some relevant info is missing. For example, it's the WM that is responsible for positioning windows. With KWin, I see no problem.

it becomes 100%, but then if you click outside the terminal and then reopen it, it reopens in the middle instead of reopening at the top. I also added that kwindowsystem is the window manager

It doesn't happen here; everything is normal.

kwindowsystem isn't a window manager. Please find the WM you use. Do you use QTerminal under LXQt or under another DE/session?

`Please find the WM you use.

$ wmctrl -m

Name: Xfwm4
Class: xfwm4
PID: 1316
Window manager's "showing the desktop" mode: N/A

Do you use QTerminal under LXQt or under another DE/session?

$ echo $XDG_CURRENT_DESKTOP
XFCE

OK, thanks! You use Xfwm4.

This may be about some (hidden) Xfwm4 setting, or even a bug in it.

@stefonarch, if I correctly remember, you have a session with Xfwm4. Does this happen there?

I can reproduce the issue with xfwm4 4.18 on Arch. The terminal position passed to setGeometry() is correct [1] (100% width at the top). Needs to investigate why it doesn't work under xfwm4.

Needs to investigate why it doesn't work under xfwm4.

There are tricks for making most X11 WMs behave correctly regarding position requests. I think one of them is used in LXQt runner — I've also used another method in one of my apps — but some WMs may be stubborn.

[yan12125]

Tricks for specific window managers is less than ideal. @amab8901 Could you report the issue to xfwm4 developers instead?

[tsujan]

I agree.

Changed the title to prevent misunderstanding.

[stefonarch]

I can confirm the issue both on arch and debian in VM.
