I confirm:

• that I have checked whether there are updates for my system available.

Symptoms

The game works fine. Proton 7.0-5 can't play videos. Using Proton GE 7-42 the cinematics work but with very low performance and stutter.

Reproduction

• Install IXION
• Run the game. In the menu launch New Game
• A signal test screen will appear where a cinematic should be.

The report identifies Proton 7.0-5, Proton GE 7-42, IXION, and a reproduction path through New Game and its signal-test cinematic, but names no source file or test. Start by reproducing the video playback and performance differences between those Proton versions; done would require an identified fix or documented resolution for the cinematic behavior.
