Hi Tom, I'm seeing the same behaviour as Harry. Toshiba satellite laptop with ubuntu hardy. I can view equirectangular tifs and jpgs up to 2050x1025, but anything larger than that just displays as white. It doesn't appear to be a power of 2 issue, since powers of 2 above 2048 are all white, and non-powers of 2 <= 2050 display fine.
A couple of other things: (1) The display responds nicely to keyboard input, but doesn't respond to the mouse (perhaps that's just because you haven't implemented it yet?). (2) The up and down arrow keys work as one would expect when viewing equirectangulars (up arrow pans up, down arrow pans down), but are reversed when viewing QTVRs and cubic panoramas. The display quality is excellent on my system, considering that I haven't been able to view anything > 2050x1025. I think this is going to be a really superb viewer when you've got some of the bugs worked out, Tom. Nice work!
