• I am able to reliably reproduce the issue on the latest stable or canary version.
• I am not using an unofficial build (Flatpak, Emudeck, etc.).
• I am a silly goose and didn't read these boxes.
• I am a silly goose and DID read these boxes.

Description of the issue

OpenGL backend does not have the issue.
Xenoblade Chronicles X DE renders correctly with Vulkan on the same system.

Reproduction steps

Use Vulkan.
Wait until the "Press A" screen appears.
