Safari windows do not work properly on external display

Safari windows don't work properly (or at all) when I have them on my external display. Pages won't scroll, websites won't load, videos won't play. I don't experience any issues with any other app or browser on my external display, only Safari. No issues when I'm using Safari on the main display of my MacBook Air. When I drag the window back to the main display, everything works fine. When I drag it to my external display, it's as if the browser is frozen.

This issue has persisted for a long time now, even before updating to macOS 26. I've tried restarting, reconnecting the display, and changing the refresh rate. Safari just doesn't work, and only Safari.

EDIT: Issue doesn't persist on Safari Technology Preview, which I started using as a workaround.

Some information:

Safari Version 26.0 (21622.1.22.11.14)

macOS Tahoe 26.0

External display: Asus MB16AHG
