Hello

if I open the URL and minimize the window and restore it again, then often I have transparency areas in the Flash content.

Tested with
a)
layers.accelerate-all;true
layers.prefer-d3d9;false

b)
layers.accelerate-all;true
layers.prefer-d3d9;true

If I set layers.accelerate-all = false the problem not exist.

Reproducible: Sometimes

Steps to Reproduce:
1. open the URL
2. minimize the window
3. restore the window

Actual Results:  
The Flash content has often transparency areas

Expected Results:  
normal behavior as it is with layers.accelerate-all;false

I suspect this is bug 593839.

Seems to happen only with D3D _10_.

Let's see if it's fixed after bug 593839 landing.

Sorry for the spamming but this happens with D3D 9 also if the preview of Flash
10.2 is installed. With the regular Flash release (10.1) this only happens with
D3D 10 on this system but not with D3D 9 (layers.prefer-d3d9;true. May be useful information if this is not fixed by the landing of bug 593839.
