Hi - just wanted to share a new issue since upgrading OS to Sonoma.
Everything seems to be working fine EXCEPT for the liquify tool, which intermittently suffers from severe lag. The lag generally only occurs when background layer(s) are set to visible, and doesn't always happen, even when working the same filem and without restarting Photoshop. So far as I can tell, this lag isn't occuring with any other tools (large brushes, transform tools, adjustments etc).
Using 16gb M1 imac (latest generation), and have necer experienced any lags prior to OS upgrade.
Problem also does NOT seem to be dependent on canvas or file size.
I know Photoshop hasn't yet been fully tested for Sonoma, so wanted to flag this issue for the devs.
