Hello,
This is a symptom of a DPI scaling bug that happens when a native app frame hosts a modern WebView2 component across screens with differing zoom levels. Every time you press a key in the message box, the embedded web page triggers a visual reflow.
I want to gather a bit more diagnostic data before figuring out the best override target or configuration change for your multi-computer environment.
Could you check your Windows display settings and tell me which monitor is currently designated as your main display? Along with that, please pull up your installed Windows apps list and grab the exact version number shown for the Microsoft Edge WebView2 Runtime on one of the affected machines.
