Import of imgs and Sprites not shwoing in UI

Somone shoud kill me

Hm, can you file a bug report with your project?

i can try later ATM i unistalled it and installed 5.4 again to work on some old project, sorry , but will give update as soon i install 5.6 again

This issue occurs because you are using ‘Screen Space - Overlay’ camera Render Mode. You could either put your sprite into UI Image (UI > Image in the Hierarchy) or change the camera render mode to ‘Screen Space - Camera’. This way the sprite will be rendered.
This is not specific to Linux, by the way. I did not observe the black artefacts, however.

OMG I AM IDIOT i redone whole project from start in 5.4 cuz i put those gold stars as gameobjects insted UI elements. I SHOUD DIE

Sorry for harassing you with idiot stuff like this , i go find a tree and some gold rope
