Public bug reported: PPA containing a more recent GTK+: https://launchpad.net/~attente/+archive/ubuntu/gtk-mir
Under U8, GTK+ windows don't render when the width and height are both >= 479. If the app starts at a size larger than that, the window will initially appear entirely black. Once resized < 479 in either dimension, the window will render properly. After that, when resizing larger than 478x478, the window only upscales the most recent framebuffer contents. I haven't 100% confirmed that this is not GTK+. However: - This bug does not occur when tested with miral-shell - GTK+ is receiving configure events for surface resizes - GTK+ is re-creating cairo surfaces that match the larger size - GTK+ is still calling mir_buffer_stream_swap_buffers_sync at larger sizes - I don't think this specific 478/479 number is coming from GTK+, the initial/min/max sizes aren't that close to it ** Affects: unity8 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662602 Title: GTK+ windows don't render when larger than 478x478 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1662602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
