The initial fix that tweaked the accept timer for the content picker dialog was a red herring. It seemed to work but it was most likely timing related.
As of now I cannot repro the scenario highlighted above: waiting a bit after the picture appeared in the composition dialog before posting it to make it work. After inspecting the logs, I found this suspicious line [0819/192717:ERROR:gles2_cmd_decoder.cc(8216)] [GroupMarkerNotSet(crbug.com/242999)!:8CA7A591]GL ERROR :GL_INVALID_ENUM : glReadPixels: format was GL_BGRA_EXT right after posting the image, and that does not appear in other non mako contexts. It *might* (still under investigation) be triggered when twitter reads back from the canvas that displays the image in the message composition dialog to get access to its content ... and seems be gpu related (GL_BGRA_EXT not being supported) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1403089 Title: pictures uploaded from gallery are plain black on mako only Status in Canonical System Image: In Progress Status in The Webapps-core project: In Progress Status in webapps-sprint: In Progress Status in webbrowser-app package in Ubuntu: In Progress Bug description: When I upload a picture to twitter via the webapp from my Ubuntu phone, the pictures appear as just plain black in the web.
