Michael, this was reproducible on windows 7 fusion Version 8.5.3 (4696910)

It does crash with several attempts of refresh, but my stack dump seems to be different.

The error message is:

Assertion failure: [GFX1]: Failed to create DrawTarget,Type: 3 Size: Size(8192,8192)......

It seems to be relevant to bug1290831 since both allocates a 256MB memory for graphics use.

I think it is another malloc failure case just like bug1290831.

The page requires a 8192x8192 DrawTargert which is a whopping 256MB chunk of buffer, leading to a memory allocation failure and hit the assertion.

Maybe we should do something about this kind of memory failure since it may happen frequently if the running environment is a low-end PC.
