power indicator freezes wingpanel when combined with Logitech receiver

I have been using elementary OS for a few months now and the wingpanel always worked correctly and well. A while ago, I got myself a pair of Logitech devices (mouse and keyboard) that connect to my computer through their unifying receiver. Since Logitech doesn't have its official software for Linux, I installed Solaar. Shortly after, the wingpanel began to freeze very often so I then removed solaar using sudo apt-get purge solaar. The problem is that even after removing solaar and restarting, the unresponsive wingpanel problem persists. Note that this problem only happens when the Logitech receiver is plugged in. I'm not sure if this problem is related with Solaar or not.

I have narrowed down the problem to the power indicator. Uninstalling it fixes the issue, but obviously I'd prefer to keep it and use my Logitech devices if possible. I believe the problem is due to the extra battery indicators on the dropdown showing battery levels of my mouse and keyboard.

Please let me know if you need any more information. I'll add a screenshot of the dropdown power menu with 2 extra indicators if wingpanel stays responsive for long enough.
