musescore crashes when using the arrow keys

• Jan 24, 2023 - 16:34

Hi,

my MuseScore 4 application consistenly crashes while composing. This happens after a while, if I am shifting the note height with the arrow keys up or down. This does not happen immediately with the first keystroke, but always uccurs in a session in the first 15 minutes after about 5 to 20 strokes(up or down). Does someone share the same issue? I was able to reproduce the error multiple times with different scores and instruments. Below, I attached my short test score:

best regards
Eric

Can you give precise steps to reproduce the problem? I tried a few random things (moving the one note way up and way down and back) but could get your score to crash. I have occasionally seen something similar though - just far too rarely to be able to come up steps to reproduce.

With my new experience from testing, now I would guess that this error is related to the playback functionality.
It keeps crashing when editing the "nameless test.mscz" file (with the 2 notes only) by doing the following 3 steps:
1. move a note
2. playing the notes
3. repeat from 1.

It took with these few notes, I would estimate 30 to 50 cycles (step 1.-3.).
I can also reproduce the error with the other file "crashTest2.mscz". Here I play the whole piece and pause the playback. Then I pull up and down the last note -> it crashes.
Forthermore, if I open the second file, wait for like 1-2min, pulling the last note up and down(from max to min, 2-3 times), the application crashes aswell.
