I am trying to run Unity3D on Elementary Juno which is (basically) Ubuntu 18.04 underneath with the Pantheon desktop environment as the UI. When I run Unity, I get the screen to open a project and everything seems normal. However, after selecting a project (or creating a new one), the Unity window appears, but the actual editor screen does not load in the window. The screenshot below shows what I am talking about. In the screenshot, I have opened a project in Unity, but instead of seeing the editor inside of the Unity window I see my desktop background. Inside the Unity window is like an image of my desktop when I launched Unity. https://imgur.com/xpgPvQI Has anyone experienced this or know what I can try to test? I'm not sure how to describe the error so I haven't been successful at finding a solution on Google. I think it's a...compositing issue? Or a redrawing issue? I think the issue could be with my gpu drivers, but I'm just not sure. I can interact with the top menu buttons (File, Edit, Window, etc). I can drag the window around, maximize it, and close it fine. But I cannot see or interact with anything in the area that the actual Unity editor should show. My GPU is a Nvidia GTX 960. I am using the proprietary drivers on Linux. I have gone into the Nvidia Powermizer settings and changed the performance to max performance. glxinfo | grep version returns: Code (csharp): server glx version string: 1.4 client glx version string: 1.4 GLX version: 1.4 OpenGL core profile version string: 4.6.0 NVIDIA 390.77 OpenGL core profile shading language version string: 4.60 NVIDIA OpenGL version string: 4.6.0 NVIDIA 390.77 OpenGL shading language version string: 4.60 NVIDIA OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 390.77 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 GL_EXT_shader_implicit_conversions, GL_EXT_shader_integer_mix, Note that my OpenGL version is 4.6, but at the top of my Unity window it says OpenGL 4.5. Could it be something with that? If so, then is there a way to downgrade my OpenGL without breaking stuff in my system? Or can I downgrade and run the downgraded version only for this application? I checked all the dependencies listed in one of the sticky posts and I have all of them. I have this error using two methods of installing Unity: 1) Installing Unity with the latest UnityHub AppImage. 2) Installing Unity based on the instructions here: https://askubuntu.com/questions/1077816/how-to-install-unity3d-on-ubuntu-18-04. One interesting thing is that with this method, everything works if I run Unity as root 'sudo unity3d'. However, opening a project as root makes some of the files be owned by root so I can't open it as non-root again. Currently, I am using UnityHub. If I run UnityHub as root, then I still see the problem. Does anyone know what may be wrong or what I can test for? Any help is appreciated.
