Upfront Information

  • Fvwm3 version (run: fvwm3 --version)
    fvwm3 1.0.4 (1.0.3-55-gef5ef5f1) with support for: ReadLine, XPM, PNG, SVG, Shape, XShm, SM, Bidi text, XRandR, XRender, XCursor, XFT, NLS (the latest commit of the master branch)

  • Linux distribution or BSD name/version
    Arch Linux (Linux 5.12.10-arch1-1)

  • Platform (run: uname -sp)
    Linux unkown

Steps to Reproduce

  1. Turn a window to fullscreen mode using the Maximize fullscreen command bound to a key in the fvwm config file.
  2. It works and the window is now fullscreen.
  3. When turning the window back to normal using the Maximize fullscreen command again, the window turns back to normal but the _NET_WM_STATE(ATOM) property still has the value _NET_WM_STATE_FULLSCREEN (I used xprop to check that). I don't know what this means exactly but it seems to cause problems with programs like GLava that check if a window is fullscreen before rendering.

Shading, minimising, sticking or changing the layer of a window clears the property from the window.

It can be reproduced with this small config file :

Key f W M Maximize fullscreen toggle

It also happens with fvwm 2.6.9.

Expected Behaviour

The property should be cleared when exiting fullscreen.

Extra Information

when using pkill -USR2 fvwm3 and reproducing the bug, fvwm does not log anything to ~/.fvwm/fvwm3-output.log :

[1624104810.188065]  log opened (because of SIGUSR2)

When a window comes out of being maximized (or fullscreened), ensure we
restore the _NET_WM_STATE property to what it was before being
maximized.  Not doing so keeps the maximized hint on the window when it
isn't in that state.

Fixes #545

Hey @gvnlch

Yup, that's a bug alright. Please can you checkout ta/gh-545 and test it for me?

Thanks,
