Sequoia 15.7.4 dock glitch on external display

[romch]

Greetings!

I have a MacBook Pro 2019 i9 with Radeon Pro 5500M graphics running Sequoia 15.7.4 and LG 4K external display connected.

I experience a dock glitch when using external display - a semitransparent square rectangle appears below dock icons when I minimize application windows. Sometimes it doesn't happen. It disappears when I click anywhere. It is funny the glitch is not visible in screenshot, I had to take a photo of the screen with my phone. It only happens when dock is on external display, doesn't happen on build-in display.

I assume it might be a video driver bug or something and it is somehow related to window minimize animation. Does anybody experience the same issue?

Thank you!

Reconfigure the dock to be vertical on the left-side of the display. Do you still see the square?

Yes I do, doesn't matter if the dock is on the left or right or at the bottom. I also tried to reproduce with guest user - same issue, so not related to my user account.
