• The previous version of Safari Technology Preview worked well

Hello! Could you share more information about the error? Is it a crash? You can open Console.app and inspect Safari Technology Preview crash reports to know! https://support.apple.com/en-ca/guide/console/cnsl664be99a/mac

I have 2 external monitors, one is connected directly to the Macbook Pro. The other is through a Dock with DisplayLink.

Everything has worked well until when updating to version 227 of Safari Technology Preview it started doing this:

1. If I leave the window on the monitor connected by DisplayLink and wait for the computer to show the screen saver and react the equipment. The browser closes with this error:

The error report is: https://pastebin.com/BSnUEuAk

If I repeat the process leaving the window on the monitor that is connected by USB it does not close.

Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. If you post the Feedback number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports.
