Image transitions "hanging" #51
Description
I have observed the following issue occur repeatedly on multiple instances of slide running on Raspberry Pi Model A+ devices set up as electronic picture frames:
Slide is being run using the following options:
slide -t 15 -T 1 -a a -r -b 30 -o 80 -p /mnt/AllPictures
Every couple of minutes, slide will begin to transition between pictures, but "hangs" around 50% of the way through the transition. This leads to "ghosting" occurring as the new picture is half-superimposed over the old picture. This persists until the 15 second timer triggers, at which point a new picture will load; however, the transition at this point simply does not occur, and the new picture loads "instantly."
This is an example of the behavior; the red circles highlight the "new" picture which did not fully transition.
