Hi Photoshop Beta Team,
After updating to the latest Photoshop Beta (around Nov 25, 2025), the “Image → Trim → Transparent Pixels” feature no longer works — it doesn’t trim transparent areas even when they exist.
I tested the same file in the regular (non-Beta) Photoshop and it works perfectly, so it seems to be a Beta-specific bug.
Environment:
・"Photoshop Beta 27.3 (or whichever version you see in Help → About)"
・"Windows 11"
・"The issue occurs even after resetting preferences and restarting."
Please check if this is related to the new canvas rendering (UFL) system.
Thank you!
