Do you use lossless rotation? Do you use 'rotate based on EXIF orientation'?

:) Hello !

• It seems that's random, for instance it occured here while the PC ran for a long time (let's say : 2…3 days).
- At this moment after a shut down and reboot, I can't reproduce either using the same file !
- I could reproduce from the 90°-R button of the JPEG box (that's opened from the main JPEG button in the tool bar,
and not from the menu). :?

i noticed this happens only the first time one uses lossless jpeg transformation,
rotating the second time one the same picture just works fine then, so maybe you want to make a copy of my uploaded picture first.
