Bug Description

[regression] Surfaces vanish as soon as their edges touch the edge of screen.

Test case:
1. Alt+drag a surface to the edge of screen so its edge goes slightly off screen.

Expected: Most of the surface is still visible on screen.
Observed: The entire surface vanishes as soon as its edge touches the screen edge.

This probably happened in the recent renderer work this week.

Found the cause. It seems "not touching the logic" but changing how it is called was optimistic...

  compositor:
  transition occlusion detection from operating as a filter/operator on mc::Scene to simply operating on the renderable list generated by the scene. The detection algorithm remains the same (note: I did not touch the logic on the occlusion detection, just changed from an operator to a function).

---------------
mir (0.1.8+14.04.20140411-0ubuntu1) trusty; urgency=medium

  [ Daniel van Vugt ]
  * New upstream release 0.1.8 (https://launchpad.net/mir/+milestone/0.1.8)
    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
    - mirserver ABI bumped to 18. Shells need rebuilding.
    - Server API changes affecting shells:
      . GLRenderer::tessellate() changed syntax.
      . graphics::Platform::create_display() has a new parameter allowing you
        to customize the compositor's (E)GL configutation.
      . Renderable::buffer(unsigned long frameno) is now:
        Renderable::buffer(void const* user_id). See below.
      . Renderable::should_be_rendered_in() is replaced by a more natural:
        Renderable::visble()
      . input::Surface::name() returns by value instead of reference now,
        to ensure future thread safety.
    - Switched EventHub device enumeration and hotplug to Udev. NOTE! This
      means mir_test_* can't run natively on touch devices any more without
      some setup first:
        sudo mount -o remount,rw /
        sudo apt-get update
        sudo apt-get install -y umockdev
        umockdev-run -- bin/mir_unit_tests
    - Added logging for HWC events.
    - Continued consolidation of Surface classes toward a simpler architecture.
    - Introduced "RenderableList" as the way to sample the Scene contents,
      and started using that in the default compositor.
    - Introduced physical length units and conversion (geometry::Length) in
      preparation for arbitrary DPI rendering.
    - Added some decorations to demo-shell; shadows and basic title bars, all
      anti-aliased and high-DPI scalable.
    - Multi-monitor frame sync has been redesigned to eliminate the need for
      frame number tracking.
    - Bugs (and enhancements) resolved:
      . [enhancement] Please move input detection to libudev (LP: #1237784)
      . [enhancement] Add a clamping resize mode to GLRenderer (LP: #1259887)
      . [regression] Intermittent loss of multimonitor frame sync
        (LP: #1290306)
      . [enhancement] Make GL config options configurable (LP: #1290780)
      . memcheck-test doesn't test anything when DISABLED_GTEST_DISCOVERY is
        enabled (LP: #1291876)
      . "Error opening DRM device" is always followed by "Unknown error -(some
        negative number)" (LP: #1292384)
      . Rendering/composition gets stopped early (LP: #1293896)
      . Ubuntu Touch Settings and terminal apps are not rendering correctly on
        rotate. (LP: #1294048)
      . [regression] Apps are much slower to open (LP: #1294051)
      . Settings app opens to a blank screen unless given enough time to render
        or the app is touched (LP: #1294053)
      . TestClientInput/DemoPrivateProtobuf memory leak is causing regular CI
        test failures (LP: #1295231)
      . OSK touch events "fall through" and hit surface behind them
        (LP: #1297878)
      . [enhancement] add a test for composite of last client post
        (LP: #1298596)
      . [regression] Surfaces vanish as soon as their edges touch the edge of
        screen (L...
