// Quite subtle issue here. Since we share the DistortedEffects object between the mOffscreen |
|
| 185 |
// and mScreen surfaces, we cannot render both of them in one go using the same time. That |
|
| 186 |
// would make the second render, in this case mScreen's render, re-use the values of the |
|
| 187 |
// Dynamics calculated the first time around and we don't want that (mOffscreen's scale and move |
|
| 188 |
// are different! What would happen is the mScreen would be - one render when we are 'saving' - |
|
| 189 |
// get drawn with different dimensions and on-screen position, i.e. we would see a flash. |
