Signal CPU use climbs very high after a few hours

I’ve been using Signal about a year now without too much trouble. In the last couple months though, I’ll notice after a few hours that my fans speed up and windows shows Signal eating up 10%-15% of my CPU. If I restart Signal, CPU use returns to it’s normal 1%-ish range…for a while and then it spikes back up.

What could cause it to become so resource heavy over time? I’ve tried a few different themes with the same result.

You could try checking with “Process Explorer” what’'s consuming CPU during usage overtime.
