Performance glitching after using show/hide instrument functionality
I know most people won't use it this way, but it's a glitch nonetheless.
Step 1: Play a piece with more than one instrument;
Step 2: Hide one of the instruments using the hide/show instrument in Properties, and show it back again
The audio should start glitching, and not playing back again from where it started (and from where it shouldn't even have stopped playing).
I was using Muse Sounds.
