Corner radius is off in MP4 videos

[jbengler]

Hi @AvdLee
I was just trying to use RocketSim for screen recordings and found this bug.

Describe the bug
In exported MP4 videos the corner radius is off.

To Reproduce
Do screen recording on iPhone 17 simulator. Save to MP4 file.

Expected behavior
The corner radius of the captured screen should match the bezel corner radius.
