Palettes Missing

S2 - Critical

A severe issue with the Basic and Master Palettes occurs every time I open Musescore Version:, Revision: 57d770e.

Today, I installed the latest update. However, when I open Musescore, both Palettes were "blank, empty."

Step 1: Restarted the computer after the latest update installed.
Step 2: Opened Musescore
Step 3: Opened both Palettes. Basic is consistently "blank" and the Master Palette comes-and-goes.
Step 4: Repeated the process and got the same result.

Opened Musescore 10 times and still had NO information or functionality of the Palettes.

NOTE: The workaround was to Create a Custom Palette from the choices given.

Maybe, I should reinstall the update.

  • Which OS version do you use? Is it Windows 10?
  • Did you use MuseScore 3.3 version and did it work for you?
  • If you are using Windows, could you please send some debug information which may help in diagnosing the issue? To obtain it you would need to do the following:

1) Create a text file.
2) Copy-paste the following content to that file:

set "QT_LOGGING_RULES=*.*=true"
"%ProgramFiles%\MuseScore 3\bin\MuseScore3.exe" > musescore_log.txt 2>&1

3) Save the file.
4) Rename the file to something like musescore_log.bat (the important part is .bat at the end). If a dialog pops up, confirm changing the file extension.
5) Double-click that .bat file.
This should launch MuseScore (it may run slower than usually). When MuseScore starts, close it.
6) Find musescore_log.txt file in the same directory where this .bat file is located and attach this file to your message here.

  • It may happen that this instruction may help you to work around this issue for a while, if you could try it and write here if this helps you avoid the issue this would be very helpful too.

Sorry for this long list of questions and suggestions but I hope this helps to find the cause of the issue.

Hi dmitrio95,

I'm getting what sounds like exactly the same issue on Fedora 31 with mscore-3.3.4-1.fc31.x86_64 (and/or mscore-fonts-3.3.4-1.fc31.noarch).

I asked about this on #musescore on Freenode yesterday and was advised to report in here, as my palettes sidebar is completely blank.

I successfully captured a log according to your instructions using the command "QT_LOGGING_RULES='.=true' QT_LOGGING_TO_CONSOLE=1 mscore -F".

However, your website is sufficiently broken that it refuses to let me attach the log. Every time I try to attach it, it silently fails. It does, however, let me attach this screenshot.

Please fix your website such that uploading logs works and I would be more than happy to upload it.

I should also note that launching with QT_OPENGL=angle or QT_OPENGL=software behaves exactly the same. In both cases, the palette sidebar is completely blank.

Hey. I had now the same problem with the empty palette in ubuntu 18.04 because i compiled a newer version. I fixed this problem by installing this files: qml-module-qtquick-controls2; qml-module-qtquick-window2; qml-module-qtquick2; qml-module-qtgraphicaleffects; qml-module-qtqml-models2

i hope this helps :)
