I finally came around to bisecting this. When an ingame resolution with 32 bit
color depth is selected, there is visual corruption when scrolling the screen
up. Scrolling in other directions seems fine. Selecting 16 bit color depth also
shows no corruption. Bisecting led to this commit:

commit 1632b8e7a419ebf256c4a356a58d505ef918f2fe

    wined3d: Use WINED3D_LOCATION_CLEARED for the initial location of textures.

There is also this message logged by the game itself:
C:\preuni\dev\bos\game\gui\woptions_menu.cpp(1023): warning: back buffer width
inconsistent with display options
C:\preuni\dev\bos\game\gui\woptions_menu.cpp(1028): warning: back buffer height
inconsistent with display options

Attached is a screenshot showing the corruption and the log from wine.
This this on an AMD 6600 XT (radeonsi navi23 ACO DRM 3.64 7.1.1) and mesa
26.1.3 but has been there with different versions since the commit.

Does the demo exhibit the same behaviour?

Have you tried Wine 11.12? It may already be fixed.

Yes, I now tested both the demo and with latest git and the corruption is
there.
