Bug ID: 55035 Summary: Penumbra: Overture Demo: in game black screen when "Post Effects" setting is on Product: Wine Version: 8.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: matheus.venturini@acad.ufsm.br Distribution: ---
Created attachment 74596 --> https://bugs.winehq.org/attachment.cgi?id=74596 Screenshot of Penumbra with WIne 8.10
Steps to reproduce:
1. Download the Penumbra: Overture demo (https://www.moddb.com/games/penumbra-overture/downloads/penumbra-overture-de...), the installer will ask if you wish to install OpenAL which is required to run the demo 2. Launch it, make sure the "Post Effects" setting is ON in the Options->Graphics->Advanced screen 3. Click on New Game in the main menu and choose any difficulty, the first cutscene can be skipped by pressing Esc
Nothing will be rendered resulting in a black screen with the sole exception being the hand/eye icon if the mouse cursor is over an item that can be interacted with, which can be seen in the screenshot I've attached.
This is similar to issue 54787, but the creator of that report mistakenly thought it was exclusive to Proton. The issue happens with vanilla Wine 8.10.
Turning the "Post Effects" setting OFF will make the game render as it should, but from my experience there will be no lighting whatsoever, resulting in the entire game being very dark (this can be seen by turning on the flashlight or glowstick, which will not actually illuminate anything in the environment).
