Cannot launch Musescore in KDE


#1

Hi.
I have my system up-to-date. It’s originally Manjaro KDE with XFCE installed later too.
Today I tried to launch Musescore in KDE and I couldn’t. I logged in XFCE and there I was able to launch Musescore.
I tried several times to launch Musescore in KDE using the Terminal and most times it displays error messages and doesn’t launch, but sometimes it rarely works.

Here are the commands I used and the error messages I got in the terminal at three times that Musescore failed to launch:

$ mscore %F
Internal error: shortcut not found
cannot find shortcut
initScoreFonts 0x2087b20
*** Error in `mscore’: corrupted size vs. prev_size: 0x000000000205b040 ***
Aborted (core dumped)

$ musescore
Internal error: shortcut not found
cannot find shortcut
initScoreFonts 0x23fe1d0
Creating interface for ScoreView object
AlsaDriver::write: snd_pcm_avail_update() (Broken pipe)
AlsaDriver: recover: stat = 00, xrun of at least 359.973 ms

$ musescore
Internal error: shortcut not found
cannot find shortcut
initScoreFonts 0x233ac00
*** Error in `musescore’: corrupted size vs. prev_size: 0x00000000022c7270 ***
Aborted (core dumped)

And here are the command I used and the messages I got in the terminal when Musescore launched the last time I tried:

$ musescore
Internal error: shortcut not found
cannot find shortcut
initScoreFonts 0x2bb5c20
Creating interface for ScoreView object
AlsaDriver::write: snd_pcm_avail_update() (Broken pipe)
AlsaDriver: recover: stat = 00, xrun of at least 352.176 ms

Can anybody help me with this?
Thanks in advance.
