I recently bought a new laptop, with Intel i5-5200U HD graphics 5500 and AMD Radeon R5 M230 2GB and 8gb ram, and heres what happens with my Unity: If open it, minimize it and then maximize again, it'll render some weird black screen in random areas of the editor, like this:

enter image description here

enter image description here

But, if I instead of minimizing unity and just opened other window , when I go back to unity nothing happens, no black weird "squares". So this just happens when I minimize unity itself and then maximize it, if I maximize another program over unity and then open unity again, it will not happen. Can anyone please tell me why this happens??? I always have to restart unity.... Is this a problem with my video card? plz help

  • \$\begingroup\$ You have dual graphics, I'm not currently aware of how AMD implement this but you should try setting it so that Unity only uses the 'high performance' graphics. There's probably a driver utility to let you do this. Essentially, try forcing Unity not to use the Intel graphics. I've had a few problems with the editor having graphical glitches and corruption and forcing use of a dedicated GPU normally clears them up. \$\endgroup\$ – Joe Apr 15 '16 at 11:27
  • \$\begingroup\$ Idk how to do that, i tried disable intel graphics but it didnt work, i tried run unity from amd control panel but it didnt worked too, idk what to do, and its just with unity \$\endgroup\$ – khofez Apr 15 '16 at 14:00
  • \$\begingroup\$ This looks like an engine bug you should contact Unity support about. \$\endgroup\$ – DMGregory Apr 15 '16 at 17:04

If you have dual graphics: force Unity not to use integrated graphics, and then restart Unity.

I switched from Intel integrated graphics to nVidia graphics for Unity in

NVIDIA Control Panel 
  -> Manage 3D Settings
    -> Program Settings
      -> Unity
        -> High-performance NVIDIA processor

This solved the problem for me.

  • \$\begingroup\$ Thanks! but a dude on unity support helped me, i just switched the render from DX11 to DX9 and everything is cool now, he said it was a known bug, so, yea, thanks anyway =) \$\endgroup\$ – khofez Sep 8 '16 at 20:14

According to this thread, an issue similar to this is known and a fix is in the works.

As a temporary workaround, users report that running Unity with the command line flag:


will force the editor to run single-threaded and stop the issue from occurring.

You can add this flag to the shortcut you use to run Unity. Let me know if you need instructions how.
