15-30min of Modding Required | Probably the Worst Compatibility Issue I've Seen.. Since I've Started Making Reports on ProtonDB.

Interacting with that top Window will cause the window to tweak for like .5sec
Go into Desktop Mode, Start the VN, Enable Window Mode in VN Settings, Top Window will display KiriKiri Engine Options | Advanced Settings ---> Multi-Thread Drawing --> Select: AUTO or 8-Threads
You need the above Command Prompt exactly as written.. Otherwise the Proton/WINE won't use the modified.dll file properly, other then that.. Everything is works 100% fine once you follow the guide I've mentioned.
Even if Valve fixes "Access Violation", the real issue remains the files inside the VN's directory themselves.. (Specifically d2d1.dll) Do not run right inside of WINE/Proton PREFIX & you will need to install a modified version of that .dll file to make it[Game.exe] work appropriately. Follow the ⬆️Guide above⬆️ / I have automated the .dll Download & installation process & you will need to use Protontricks to fix the Opening / ED Movies.

ACCESS VIOLATION: W/O a Custom .DLL file this VN is currently borked as of Proton 10-1.
This is a.. More recent KiriKiri VN Bug that has made its way back, before it effected all KiriKiri titles, but Valve fixed it. Though I'm not really certain that Valve can fix this issue since the current solution is to apply a custom .dll file that the developers would have to add to the VN's directory, but this is a Linux-Only problem..................... So that's never going to happen.

Access Violation: The thread attempts to read from or write to a virtual address for which it does not have access.

Game needs a custom made dll for kirikiri games to avoid graphical degradation. DLL and Source code can be found on: https://www.vnwiki.xyz/visual-novels/sickly-sister.html#steam-deck

With Proton-GE 10.3, I still need to apply wmp11 fixes or my game would still crash after the logo intro. Played on Deck OLED in Game mode
