[d3d9] Flickering Issues with KiriKiri titles
Can already tell that these are going to rely on partial presentation in one way or another and are essentially desktop apps in a trenchcoat. Would just recommend using wined3d for these, it's not something we can support at the moment.
Here's the log. did things in the game that cause all the flickering
With past DXVK / Proton versions (Early 2024) i dont remember this issue being a thing,
Occurs with DXVK Windows, Linux and Steam Deck. On all Proton versions
You said that it happens on Windows DXVk too right?
I cannot reproduce on Windows with DXVK 2.5.3/2.6 (Intel Xe & NVIDIA 3060) Senren Banka Steam ver.
If you can reproduce on Windows DXVK on AMD, then I would suggest it may be vendor specific issue.

@CreeperofDoom Can you run game with "-about" and find this part in the window? I think the game may use different value as default on different hardware.

Please make an apitrace.
Apitrace made on Intel native DX9. https://github.com/qinlili23333/PageConnect/releases/download/TEST/SenrenBanka_IntelDX9_apitrace.7z
Replaying with DXVK or without is both a bit weird that qapitrace generating 4 replaying window that 3 are blank each time.
Edit: The game by default use Layer mode for video rendering. There're 3 video files for splash, and it creates D3D9Device for each video then release after video finish, that's why apitrace replaying has 3 blank windows as apitrace seems won't close window after context released.
The game locks with D3DLOCK_NO_DIRTY_UPDATE each frame. May be the reason. Need further investigation.
Thank you.

Titles that use the KiriKiri Engine have annoying flickering issues when DXVK is used (Can probably cause epilepsy)
The flickering occurs every time a new sprite appears on screen. Sometimes with a permanent black screen that requires restarting the game
This does not occur on Windows with DX9
Occurs with DXVK Windows, Linux and Steam Deck. On all Proton versions
