I've attached a test case that creates a window with a list of text inside. The list can be scrolled by dragging a finger/the mouse up + down. In Ubuntu Mobile, the list is painted as a white screen instead of text.
The problem is reproducible on both the Samsung Q1 and Menlow-based devices. The test case uses the moko library, which handles scrolling the list. moko in the Ubuntu Mobile PPA is currently 0.1-20. Reverting to moko 0.1-11ubuntu1 fixes the problem on both devices. In moko 0.1-20, changing the call, cairo_paint_with_alpha(cr, 1.0) to cairo_paint_with_alpha(cr, 0.99) fixes the problem at the cost of performance. Since cairo_paint_with_alpha just delegates to cairo_paint() if the alpha value is 1.0 (fully opaque), cairo_paint() seems to be the culprit in this case. ** Attachment added: "Test case using the moko library" http://launchpadlibrarian.net/13032618/moko-test.c -- Cario_paint can NOT paint composited GtkTreeView context at Hardy https://bugs.launchpad.net/bugs/202046 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
