Auch der feine Herr Nieuwenhuijse baut von Zeit zu Zeit Fehler in sein Programm ein die dann ggf. später mit Updates gefixt werden, so z.B:
Version 11.21 (4 February 2020)
Added support for the Insta360 EVO, QooCam and QooCam 8k cameras
New option in Lens Settings tab: Mirror Horizontally. If enabled, the image will be mirrored. Mirroring is done after shifting and cropping the image, so the orientation of lens shift and cropping are not affected. This was added to support cameras like QooCam, which generate mirrored image files.
Fixed: a black line could be visible in the images generated by Publish to Website, if tiles were generated at a smaller than optimum size
Fixed: artifacts ('blocky' images) on nvidia GPUs when using lens parameters with a fisheye factor very close to zero
Fixed: 'assert failed' error if the blending mode was set to Alpha Blending and the blender subsequently set to SmartBlend
Fixed: occasional crash while using GPU acceleration
Version 11.12 (14 march 2019)
Fixed: crash at startup on Mac computers from 2010 or older
Fixed: in specific circumstances the generated panorama would contain a transparent 1 pixel wide line at the bottom or right hand side.
Version 11.8 (9 November 2018)
Fix: Windows: occasional crashing
Fix: Mac: under macOS 10.14, when using GPU acceleration, lines could be visible in the stitched panorama. This is probably caused by a bug in the macOS OpenCL runtime. To workaround this problem, for part of the blending process the CPU is used instead of the GPU. This solves the problem, but GPU accelerated stitching will be somewhat slower.
Falls Deine Version ein wenig älter ist könnte es das sein, oder aber was bis dato unbekanntes ...
