Comment 31 for bug 830949

re Ara, David and others; if I understand the situation:

  1. Hardware has a max texture target of 2048x2048.
  2. 1024 wide (internal) + 1280 wide (external) > 2048; so Unity 3D fails, Unity 2D works; error message shown
  3. 600 high (internal) + 1024 high (external) <= 2048; so Unity 3D works, Unity 2D works. Nothing shown
  4. On *some* N10 systems, somehow the machine ends up setting/enabling the impossible (2) situation, without warning

Two questions:

  a. Is the summary above correct?
  b. If so, how to cause (4) reliably?
