Identify the documented problem
KONAMI’s October 14 notice identifies some UI elements appearing partly off-screen on Steam Deck. The notice says a fix is being investigated. As of our October 16 source check, that notice does not give a completed fix or a resolution-setting procedure.
An official issue notice is not a Steam Deck Verified badge, a performance benchmark, or proof that every part of the game has been tested on the device. This page makes none of those claims.
Keep display clipping separate from launch failure
| Your symptom | Relevant information |
|---|---|
| The game opens, but some UI is cut off | This is the Steam Deck display issue named by KONAMI. |
| A Windows PC cannot start with V-Sync off and Unlimited FPS | Use the separate PC launch guide. Its Windows monitor steps are not a verified Deck clipping fix. |
| Returning to the title page prevents continuing | Compare the system-language issue. |
Report details that help reproduce clipping
Record the installed game version, whether you are in handheld or docked use, and which interface is cut off. Include a screenshot showing the whole display if you contact support. Describe any changes already attempted so the report distinguishes the original problem from a later change.
No particular Proton version, launch flag, resolution override, or FPS target is established as the solution by the cited notice. This guide therefore does not present a guessed configuration as a tested preset.
Check for an actual fix
Use patch status and known issues for the distinction between an announcement and a released update. The original evidence is KONAMI’s October 14 notice; newer official updates should be checked before repeating old troubleshooting steps.
