[OSX] RenderSurface attachment asserts on various projects, in 5.4 beta builds

Shaders

-

Steps to reproduce:

1. Open Unity;
2. Open attached project;
3. Open "1.unity" scene;

4. Notice that there are 3 planes in the scene with 3 different Shaders having uniform arrays parameters and script, processing those parameters at runtime;
5. Enter Play mode;
6. Zoom in/Zoom out by scrolling mouse wheel in the Scene view;
7. Wait for some time (10-20 seconds).

Actual result:
Weird errors appear in the console:

attach.color[0]->backBuffer == attach.depth->backBuffer
!attach.color[0] || !attach.color[0]->backBuffer

See attached actual.png screenshot.

Notes:
- Reproduces only on OSX (10.11.4), OpenGL4.1 (GLCore) mode;
- Doesn't reproduce on Windows 10;
- The issue doesn't reproduce every time;
- The other possible symptom of this failure is that Game View becomes unresponsive and following assertions appear (in addition to abovementioned ones):

!::HasAsAttachment(GLESRenderTargetSetup(m_PendingFramebuffer), rbid)

!::HasAsAttachment(GLESRenderTargetSetup(m_CurrentFramebuffer), rbid)

    Often getting this error in 5.4.0b13 play mode and it freezes my Game preview. Only solution I have found is to restart Unity.

    Sorry, I meant Unity Version 5.4.0b12.

    I'm also having this issue in 5.4.0b1. It happens about every 10 minutes and makes the scene preview unresponsive and requires a complete restart of Unity to fix. I'm on Mac OS X El Capitan 10.11.1.

    I get the following errors in the console when it happens:

    !::HasAsAttachment(GLESRenderTargetSetup(m_PendingFramebuffer), rbid)

    !::HasAsAttachment(GLESRenderTargetSetup(m_CurrentFramebuffer), rbid)

    !attach.color[0] || !attach.color[0]->backBuffer

    !attach.depth || !attach.depth->backBuffer

    Getting this error intermittently in 5.4.0b10. No idea why it's happening.

    Irregularly getting this error in 5.4.0b9. It freezes my scene and I have to stop it and play again.

    I get the same error message in a simple scene with several quads, on each of which is material using a PNG with transparency (used to depict static 2D characters). Sprites/Default shaders are used and Unity 5.4
