Mobile devices, particularly those with low RAM can be susceptible to crashing when taking screenshots.
Dev Notes:
There is still a large amount of memory required for capturing (and holding on to) screenshots. We may be able to further improve this process by immediately converting the final texture to a jpg, then resizing again to a thumbnail. The output would then be a small thumbnail and a collection of bytes representing the jpg. This would eliminate the need to maintain a large texture consuming memory on both the GPU and CPU sides when collecting a bunch of screenshots.
