screenshot showing the issue

In the game 'The Egyptian Prophecy: The Fate of Ramses' text (subtitles,
in-game encyclopedia) is displayed on a bright cyan background without
transparency making the text difficult to read.

Reverting commit ee7d047dd55a4b2338eb2d64f85b7d984b39812f
on top of wine-9.0-54-g1932c3a2516 fixes the problem for me.

There is no demo version available.
The Steam version is DRM free, you can start Egypt3.exe directly, without Steam
running.
Make sure 32-bit color depth is selected in the <Options> menu (the problem
doesn't occur in 16-bit color/software renderer mode). In the main menu open
<Documentary Database> to see the problem.

Still present in wine-9.0-54-g1932c3a2516.

On the left, the correct display. On the right, the glitch.

The same problem is encountered in the game "Echo: Secrets of the Lost Cavern"
by the same developer (Kheops Studio), when hardware rendering mode is selected
(no problem in software mode).

It does a colour fill of a 32-bit RGB sysmem surface without alpha. The colour
fill has alpha == 0. It then locks this surface and creates a DC from it. The
game apparently expects this alpha to be retained even though the surface
doesn't actually have an alpha format.

Testing shows that this is the case on modern Windows + WARP, but that's not
very meaningful. It needs testing on older hardware and other drivers. I'm
working on that.

Fixed by d2ce4c3ef1a05f3457bf00f55e4ac5d42cf10a70, sorry for the delay, the
best architecture for the fix wasn't clear to me.
