@leocg @rplaye I can reproduce this as well.

Device: Samsung S23FE
Android: One UI 8.5 / 16
Opera: latest version

Same symptom as rplaye described: the bottom left corner of rounded elements gets cut off, leaving a square notch. It happens on buttons
and other rounded shapes across many sites.

Example page: https://rivana-nails.com/
The oval "USLUGE" button below the hero heading is clipped at the bottom left.

Chrome on the exact same phone renders it correctly, so it is not a GPU driver issue on the device alone.
