@Eric_E This build has broken the UI for some sites and the browser itself. 



for me it is occurring for certain child window/popups modal window taskbar that is not rendered. Kinda looks cool but I can't move the window when it pops up :p submitted feedback already but proving to be quite a challenge to use today


@dailen This is a known issue that our engineering team is currently investigating and resolving. In the meantime, you can use Beta or stable versions to avoid disruptions to your workflow. 

@dany20mh We appreciate your report on this issue. To help us investigate and resolve it, please send us your feedback from the browser with a screenshot and diagnostic data attached.

  2. Go to Help and feedback.

Multiple websites not rendering properly. They are in some sort of wide mode. Google News, Gizmodo, MLive are some examples where the sites don't seem to render correctly in this update.

@bhargavreddy  some examples where they don't render properly 



@bhargavreddy Thanks for the screenshots.  I'm unable to reproduce this.  Does it still happen with  InPrivate window?

I'm able to reproduce this now, and I have notified the engineering team. Thanks for reporting this.

@Eric_E for me is the tab bar got some UI problems, as u can see in the screenshot, the tab bar's color and tab position is messed up.



Is it me, or have the window controls (minimize-restore-close buttons) disappeared from dev tools?

这个网站(中国铁路12306网站)的日期选择控件显示异常  ,日期的文字是重叠在一起的。正式版edge和chorme浏览器全部都能正常显示。screenshot20230530.png

@Noel Burgess it's not just you! I thought I was losing my mind.




I love the new UI that is using the Windows 11 style Mica

@ybgjj2009   删除 C:\Users\???\AppData\Local\Microsoft\Edge Dev\User Data   ,并启动edge,显示正常;关闭edge后再打开edge,又恢复了原来显示异常的样子。
