I'm seeing a bug where when Trello app is open on my Mac (15.4.1) after a while it uses 100% of the GPU resources of my Mac, slowing things down, draining the battery and making it run hot.
Trello 2.15.9 (latest in store)
Doesn't seem to be a way to report the bug. Contact support just sends us to the forums.
I've noticed that it happens with a card is opened, the GPU pegs and once you close the card, the GPU use drops again. The 2 big spikes in the middle are me opening a card, leaving it open for a while, then closing it.

Anyone found a fix?
