Editor: Async Task Progress Bars

The image for this in the release notes is missing.

Iam getting some errors while running my game from inside the editor:

Assertion failed on expression: 'pos == inputBuffer.size()'

Assertion failed on expression: 'pos == inputBuffer.size()'
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Assertion failed on expression: '0 == m_CurrentBuiltInBindMask'
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Make sure the packages you use in your project are up to date.

Remove it and all the packages your are not using in your project. (That includes Visual Studio Editor which is not needed if you are on a Windows pc.)

Nice, I gonna test it right away - so far alpha 17 was kinda ok, some crashes but for most time it was stable. Glad they fixed GPU Memory Leak :smile: !
