This is caused by a recent change in the thumbnailer, which fails now to return large preview images. https://code.launchpad.net/~jpakkane/thumbnailer/memfixes/+merge/245550
The previous code has a code path for generating full resolution thumbnails, but due to a bug (that was corrected in the branch above) that code path was never hit. The branch above makes that code path accessible again, but it triggers another bug: the images are actually returned by the thumbnailer image provider not into the requested size but in the full resolution, which the GPU can not handle, so they appear black. This patch will fix the issue by providing proper scaling: https://code.launchpad.net/~fboucault/thumbnailer/thumbnail_qml_provider_respects_size/+merge/246548 ** Branch linked: lp:~fboucault/thumbnailer/thumbnail_qml_provider_respects_size -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gallery-app in Ubuntu. https://bugs.launchpad.net/bugs/1412442 Title: Images are black when opened in gallery Status in gallery-app package in Ubuntu: Confirmed Bug description: image 202 1.
