Computer lags when adding multiple repeats

I would like to know if this is just my computer, or if it is a bug in Musescore that needs to get fixed. I was working on a new piece of music, and wanted a repeat to happen more than once. I did the usual procedure where I right-clicked on the measure I wanted to add repeats to, went into measure properties, and added 2 more repeats on top of the already existing 1 (The measure was enclosed in repeat barlines), for a total of 4 plays of that measure. I played back that measure afterwards, and It caused my computer to lag excessively. I closed Musescore after I managed to get task manager open, and my PC continued to lag. I eventually had to restart my PC manually, and that leads me to where I am now. Luckily, I hadn't gone too far into composing the piece, and my computer is fine (which means it at least runs; my computer is not the greatest).
