4.6 Preview Bugs

Hello,

Here are some bugs I found when using 4.6 Preview:

  • When I have the output windows open in the editor the editor freezes more often than not. Sadly there is no crash report what so ever.

  • Making a LoadingScreen with a custom UUserWidget using the movie player crashes with some levels. This can be stopped by implementing the on mouse enter event for what ever reason. Sadly implementing the on mouse moved event does nothing. It still crashes when the player moves his mouse when the loading screen is showed:

  • This is more a feature request but notheless: I would like to see an option to set the owning user name of a session yourself, because hostname-GUID looks not so nice.

  • Other general freezes of the editor, where I also do not have crash reports

  • Sometimes when launching the editor the play on its own process crashes instantly for the whole time the editor is open. :

Greetings,

Hey DJ_Lectr0-

Are you using the preview from the launcher or the preview source from GitHub? Also, if you could create a new post for the feature request so that can be handled appropriately. For the crashes you mentioned (both with the output window and the others) if you could post these in their own post as well for assigning and tracking purposes. If the freezes/crashes do not provide a crash report could you give us reproduction steps or an indication of what you were working on when it happened (working inside a blueprint, running play-in-editor mode, etc.)

Cheers

Will do that right away. I am using the launcher version. Apart from the freeze with the output window they seem kinda random (And I dont rember when they happened exactly).
