Black Mirror 2 is a point-n-click adventure game.
When there is nothing of interest under the mouse pointer, the pointer is shown
as a silver (grey) arrow (this appears correctly in Wine).
When the mouse pointer hits a "hotspot" in the game (e.g. an object with which
you can interact) it turns red.
This red arrow is covered by a solid white box in Wine.
I can't show you a picture of this artefact simply because the white box
doesn't appear in the screenshots.
Steps to reproduce the problem with the demo:
1. Install the demo as usual (DirectX installation is not needed).
2. Launch the demo. You will be greeted with an error message. Click on the
<Ignore> button 7 times to get rid of it (that's bug #24563).
3. You can see the white box on the screen while the game is loading to the
menu. In the menus the pointer appears correctly (it's the default silver
arrow).
4. Start a new game, skip the intro videos. When you gain control over your
character move the mouse across the screen. There are several hotspots on the
scene, when the pointer is hitting one of them it turns to a white box. If you
move the mouse quickly you can spot the red arrow, hiding behind the white box.
I found that the mouse pointer appeared as it should have in Wine-0.9.50, and
bisecting resulted:

The demo has a huge download size (1.3 Gb). I willingly provide logs or tests
if they are needed.
