    - When moving the view around sometimes you get some weird deformed geometry flashes.
    - Gizmos look like black boxes after you click on one of them.

    I'm getting the same thing on intel and nvidia gpus.

    I've noticed the same behaviour. (Nvidia driver version 358.16, open source)

    Yup, same here. Also once this starts happening, I can no longer just click on objects in the scene, I can only drag select them or select them from the hierarchy. I'm using the latest stable nvidia drivers, 355.11 (for LukaKotar, just fyi these are not the open source ones, Nouveau is. I'm not sure if the open source ones would be able to drive unity or not).

    Unfortunately for me, this makes this the most unstable build of Unity on Linux to date, bordering on totally unusable without being able to select items in the scene.

    Could be tangentially related, but I'm not sure. Thing is, I don't use Mesa for my OpenGL drivers, Nvidia rolls their own which has a version string of 4.5.0. It could be that they changed something in their graphics calls but we wouldn't know about that. The release notes says they didn't change their rendering stuff, but they must have at some point.

    I've got the same problem. I'm on Radeon 5830 with open source drivers. I start Unity with the "MESA_GL_VERSION_OVERRIDE=3.2" option.

    unity-editor-5.3.0f4

    I don't know if it's related in any way but there are some error in logs:

    I've noticed this too, just with the new 5.3 deb that was released. When running my demo it has random polygon glitches everywhere.. Almost like when I was creating a Game Engine, and I did a 'count + 1' when feeding the Vertex Buffer, so it was grabbing a vertex from random memory.

    Same glitchiness with black boxes for me, tested with both open and closed source AMD driver.

    Same happens to me. I run it with MESA_GL_VERSION_OVERRIDE=3.3COMPAT on Ubuntu 14.04 with Intel HD 3000. The artifacts from time to time appear when I move cursor from Scene view to other windows (Inspector, Console, Project). If I move camera (not only zoom it) in Scene view, or choose another object artifacts may disappear.

    Also, sometimes I can clearly see distorted image of Google Chrome's address bar when I move cursor to the Unity3D's top bar. It's not responsive (if I type something in currently opened chrome's address bar it won't affect that distorted image). It's just some image stored in the computer's memory some time ago.

    Does running Unity with -force-opengl change this behavior?

    The black squares glitch still occurs.

    Also, just to mention, I am not getting the other graphics glitch, just the gizmos turning into black squares.

    It doesn't seem to make a difference for me, at least with the intel gpu.

    On the nvidia the black gizmos are still there but I can't reproduce the polygon flashes anymore. This is using nvidia's driver 358.16 (same as before) and regardless of whether I use -force-opengl or not... I checked my logs and I upgraded mesa from 11.0.7 to 11.1.0 the same day I posted this, but I'm not sure which version I was using that when I tested :/

    No, it changes nothing.
    I also have those black squares instead of camera and light objects' icons. I've got mesa 11.2.0.

    I can also confirm this black box issue with Unity 5.3 on Arch Linux. Very nasty issue. Nvidia driver 340.96, using Nvidia GTX275. Only work-around is every time restart Unity... -force-opengl doesn't help at all.

    I noticed that the vertex flashes only happen in Quality Levels Simple, Good, Beautiful and Fantastic. Fastest and Fast work fine.

    I noticed that in editor -force-opengl doesn't even use old renderer.
