Problems with photo hub

[wuiyang]

I downloaded Windows 10 Mobile yesterday, and I having a problem with photo hub, my SD card's picture display blank, it can get the picture, but when view in grid, it becomes null. Is it my SD card reading speed slow or the photo hub problem?

EDIT: I put my photo to phone storage, now it display properly. If it is SD card reading speed problem, why I can get 1 picture fast? but 12 pictures display in grid slow?

Phone: Lumia 520

I have the exact same problem on a Lumia 1520 no matter what sd card I use.
