Can't minimize Musescore or change virtual desktop on Linux with Gnome-based desktop environments

I'm using Linux Mint 19.1 with the Cinnamon desktop environment.

If I try to minimize Musescore the window immediately re-opens. If I try to switch between virtual desktops I'm immediately taken back to the desktop with the open Musescore window.

This happens regardless of if the Musescore window is maximized or not.

I've uploaded a video showing the issue -


Are you using the AppImage, or some other version of MuseScore? The AppImage is supported and known to work on pretty much any distribution. Other builds, not so much. If it comes from a repository, could be whoever built it did something wrong.

I'm not aware of any problems having been reported with that, and it worked fine for me, but do try 3.3.4, the latest and see if the problem remains. And do try rebooting if you haven't already - seems likely to be a system issue.

Same issue with 3.3.4 after a restart.

I'll test it on my laptop, I have 3 different versions of Mint installed on it and it uses a different graphics card. I'll report back.

My results. It won't run on Linux Mint 17, not a problem, that version is very old.

So I ran it on Mint 18 and 19 with no issue. What I noticed though is because it was the first time I'd used Musescore on those installs I was prompted to configure Musescore. I haven't changed the configuration files on my PC for ages, so I tried renaming the config folder and running Musescore afresh, as expected I got the config window.

After that Musescore minimizes just fine, so there is something in my configuration folder that's causing the issue for me.

Still active I think...

I found what causes the issue and I was able to recreate this on the fresh install on my laptop. Enabling View >> Play Panel, or View >> Mixer

Also on my laptop enabling the Mixer makes the maximize button vanish, this doesn't happen on my desktop so perhaps is related to screen resolution...

In fact I just noticed the bottom of the Musescore window disappears on my laptop when I enable the mixer, so definitely a resolution issue.

I can aggree the description above.

  1. Without any additional window minimizing ist working correct.
  2. With the play panel or mixer panel minimizing doesn't work.
  3. Bottom of MuseScore window disappears, but IMO only when the dock panel from ubuntu is at the bottom
    of the screen. if the dock panel on the left or right side the MuseScore windows does not disappear at the bottom.

I'm working with a laptop too.
Resolution: 1600 x 900 (16:9)

same issue on OS: Linux Mint 19.3, Arch.: x86_64, MuseScore version (64-bit): 3.5.0, revision: 1ee2fe3
Can't minimize MuseScore window when mixer is docked. This is wierd and annoying!
Greetings, Pentatonus

I am also having this problem with MuseScore-3.4.2-x86_64.AppImage on Ubuntu 18.04.
OS: Ubuntu Core 18, Arch.: x86_64, MuseScore version (64-bit): 3.4.2., revision: 148e43f

  1. With the play panel docked right or upper left, minimizing Musescore with the minimize button causes it to minimize and immediately open back up again.

  2. If the play panel is closed or undocked the minimize button works properly.

_fix #298820: fix inability to minimize MuseScore on Linux with Gnome-based desktop environments

The issue happens if some QML view is opened, e.g. a plugin dock or,
more importantly, Palettes panel. Fixes the issue by leaving the code
in Mixer and Play Panel forcing a window to take focus only in cases
when it might make sense: when opening the corresponding widget and
when unminimizing MuseScore if the widget is in floating state (otherwise
it won't take focus). This is enough to avoid triggering the issue
which happens only if Play Panel or Mixer is docked._
