Just chucking the diff at the top of that issue into qt6-declarative did not work for me

[Jaredy899]

Wrapping it with this didn't work either.

xprop -root -remove AT_SPI_BUS

Honestly, the best Musescore ever worked on Solus was back at 3.x. Since 4.x there have been minor glitches all the time. Not sure why, but eg. Mixer hasn't worked for a long time on Solus packaged version.
