I have a SharePoint form customized in Power Apps that has been running without issue in my environment for the past year. This morning the new list experience got pushed out to my SharePoint tenant, and since then the way the form is displayed requires excessive scrolling. This has never been an issue on any resolutions until today, and is reproducible across multiple machines/browsers/users etc. I can also reproduce it across all of the Power Apps customized SharePoint forms in our environment, not just this one. No updates have been pushed to these forms in several weeks, and the only thing that changed is the new list experience was pushed by Microsoft.
With the new list look/feel the form now is a pop up in the middle of the screen, as opposed to the flyout before. Which I'd be completely fine with as long I didn't have this issue with the scrolling.
The only workaround I've been able to come with is have the users lower the zoom in their browser to 75%. When that is done it displays everything, but that's not something they are happy about and not a long term solution.
For example, this is how it looks now on a display with 1920x1080 resolution. It requires scrolling over to the right in order to see the additional fields:
On another display with the resolution at 2560x1440, it displays correctly:
I'd welcome any ideas on how I can get rid of this scrolling and have it render correctly no matter the resolution of the client machine.
