@schollexpos does pressing F11 to exit full-screen mode get the controls back for you?

@schollexpos Is this issue still actual in 4.3.2 / master?

[iainhallam]

@zacjansheski 4.3.2 still does this on Windows 10.

And the master nightly builds from https://musescore.org/en/nightly-builds?

Yup - OS: Windows 10 Version 2009 or later, Arch.: x86_64, MuseScore Studio version (64-bit): 4.4.0-241850505, revision: github-musescore-musescore-d46107f has the same behaviour. It opens on a secondary screen full-screen with no controls, and requires F11 to come out of that mode. Dragging it to the top of the main screen, it maximises, with controls visible; dragging to the top of a secondary screen, it again goes full-screen.

Now has a slightly different behaviour. My three screens are labelled 3, 1, 2 by Windows. If I maximise on screen 1 (my main screen with taskbar, etc.) all is well. If I maximise on screen 2 (the rightmost one), I now have window controls and can drag away from maximised. If I maximise on screen 3 (leftmost), the controls disappear, but now F11 makes the screen flash, and the controls don't appear. I need to press F11 again to get out of maximised mode.

I wanted to experiment whether it mattered which monitor was the "primary" monitor. In MuseScore 4.4 and Windows 11 24H2, if I make the vertical monitor my primary display, MuseScore can maximize correctly on that display, but not no longer maximize correctly on my laptop's built in monitor, because it is no longer the primary display.

The scale of the two monitors is the same at 150% (recommended), so it is not a scale difference.

MuseScore 4.4.1 does not handle the act of changing the primary display well at all. If I change my primary display to a different monitor then launch MuseScore again, it does not draw its window at all. I can not find its window until I set the primary monitor back to the same it used to be.

Now, after changing primary display with MuseScore running, its screen image becomes garbled and doesn't respond to any imput. It is just an image of its former glory, as shown in the screenshot.

However, I can force quit it and relaunch it , and it opens normal. So changing my primary display with it running is better than when not running.

[davidlbangs]

It occurs to me that MuseScore is remembering its screen position relative to whatever is the primary monitor, instead of remembering it relative to the window canvas (or leftmost monitor) like every other app does. So, if I change my primary monitor to the right monitor while MuseScore is on the right monitor, the window position is interpreted as being off to the right of my right monitor. If it is on my left monitor when I change the primary monitor from right to left, it is now off to the left of the left monitor.

This sounds off topic to this forum, but I think it is all related. MuseScore is paying attention to which monitor is primary, and it really should not. All the monitors are arranged relatively to a canvas, not to the primary monitor.

Can this get prioritized higher? I commonly have MuseScore maximized on a secondary display, and sometimes I want to move it back to the primary display. The entire title bar becomes unclickable after MuseScore 4 is maximized on a secondary display. The workarounds, which are not shared here, are...

• Right click on MS4 instance in taskbar and click "Restore" to bring it back to windowed mode
• Using [Windows Key] + Left Arrow / Right Arrow to move the window back to the primary monitor.

I would love to just be able to drag the window back from secondary to primary. Lack of support for things like this are why I still use MuseScore 3.6.2 more often than MuseScore 4.
