[Freelancer (2003)] Splash screen flickering since latest dxwrapper release

[BC46]

When starting the game Freelancer (2003), a splash screen appears briefly before the game's main menu is loaded. This video shows what the splash screen looks like normally:

If I start Freelancer with dxwrapper v1.2.7500.25 with the config

[Compatibility]
D3d8to9                    = 1

then the splash screen flickers multiple times, seemingly switching between different gamma values (WARNING: flashing images):

This issue wasn't present in the previous dxwrapper release. Considering the different gamma values, I assume it has to do with the new gamma shader introduced in the latest dxwrapper release.

Side note, if I use AntiAliasing = 1 under [d3d9], then the flickering only occurs twice and doesn't seem to be as bad as in the video above:
