You are on the right track. We addressed the issue for our general
Input::Session_component, which is also used by fb_sdl. Please have a
The fix is not part of Genode 14.11 but already in our master branch
since January 9 2015. So you could just 'git cherry-pick 0f18ecc142'
or simply apply the commit as patch to your source tree.
