Symptoms

The game launches and proceeds to the main menu but has rendering issues in the menu which prevent starting a new game or changing options. Quitting is available and succeeds.

Reproduction

Occurs every launch. PROTON_USE_D9VK=1 repeats same issues.

steam-241620.log

The game has a built-in log that is enabled by adding
CreateLogFile=1

to gfx.ini in ***/steamapps/common/Inquisitor/Game/
log.txt is created in the same directory and is attached below.

log.txt

According to PCGamingWiki the game uses Direct3D 7 for cutscenes and Direct3D 8 in general otherwise.

Start by reproducing the rendering issue described for Proton 4.11-6, then review the attached steam-241620.log and log.txt. Compare behavior with and without PROTON_USE_D9VK=1; the report does not name a source file or test, so completion would require identifying the cause and validating a compatibility fix.
