Window contents don't fill window after export?

My game plays fine in preview mode. But when I export it to Windows WebView2, objects in the window aren't adjusted to the window size on startup. Instead, they are attached to the left side of the window but don't fill the whole window. Attached is a pic to illustrate.

If I adjust the window size after startup, the objects adjust to fill the window as expected. But why do they not fill the window on startup? FYI this is a new issue, I've exported many times in the past year with no issues. Also happens with both png and webp export. This may be the first time I've exported with v308 but can't recall for sure.

Thanks

This sounds like this bug report, but when I tried it, it was working fine for me. It's hard to offer any help unless we can find out why it happens.

Ashley Yep that's the same issue, and I can duplicate it on every one of my laptops. Can you please try the project again and/or try it on another machine? I also added a comment to the bug report, can you please reopen the issue?

Thanks

Ashley FYI I saw that Beta 310 has a possible fix for this, so I did a quick export to webview2 (64 bit only, minimal settings for time), and the window contents now fit properly. I'll try a full export in the next few days, but this is very promising. Thanks so much for fixing this!!
