New Trello Upgrade - Slow Performance

Question

Dear Atlassian & Trello Team:

I just upgraded today on July 8, 2025 upon a suggestion from your product. Unfortunately, the performance is very slow on the desktop with the Chrome metrics indicating:

* About 5 seconds for the Largest Contentful Paint (LCP)

I have already disabled Chrome's graphics acceleration and disabled the Chrome extensions. I had the same amount of cards from the old Trello and had no major issues adding, moving, or removing cards.

I have Chrome Version 137.0.7151.70 (Official Build) (x86_64), macOS 15.4 (24E248).

Please let me know of any other information you require to help debug the situation.

@John Huan Vu out of curiosity, what other applications (if you can share) were slowing down because of graphics acceleration in Chrome being on?

I am also having a similar issue: cards with 20+ items on them loading incredibly slow only in the latest update.

@Andrea Crawford , I did enable Chrome's graphics acceleration and it did help. That is quite unusual. I had it disabled because it was slowly down other applications. Will Trello do any future updates so that it does NOT rely on graphics acceleration?
