Both are displaying the same layout, on the same hardware, with matching displays, identical versions of windows, with the same patches installed, and the same video drivers.
I assume the the browser emulation settings are the same on both machines as well?
The ‘Change size of text, apps and other items’ set to 100% in tho cases (Windows display settings)?
I’m happy to try and recreate the issue with your layout locally if you’d like to share your layout with me (if so please send it over private message).
