Corrupted default ui material
The default ui material on several gameobjects with graphic components seems to be corrupted. Normaly the material is displyed as "Default Ui Material" But now it displays property information instead 
This results in all the gameobjects with this bug not showing up in the scene view, but works like normal in play mode. Seems to me like the scene file has become curropted along with the new prefabs as i just upgraded to Unity 2018.3. I have since tried getting the lates version 2018.3.6f1 but it di not change anything. I have also tried deleating all Lib and temp files. 
If i rigth click the material and resett it, all graphics will show in the scene view untill the scene recompiles, then its all hidden again.
Any help is much appreciated.
