Street Fighter 5 very choppy

**Game information**
Street Fighter 5

**Distribution name and version where applicable**
Fedora Silverblue

**Flatpak info**
flatpak --version
Flatpak 1.12.7

flatpak --gl-drivers
default
host

**Problem description**
Extremely low framerate on CAPCOM logo and main menu, can't get past main menu (machine should run game fine)

**Does this issue reproduce with native Steam**
Have not tested, Proton changelog for 7.0-3 mentions "improves the performance for Street Fighter V during online matches" so I'm assuming it works!

No project files or tests are named. Start by reproducing Street Fighter V on Fedora Silverblue with Flatpak Steam 1.12.7, then compare the result with native Steam as requested in the report. Done means determining whether the choppy CAPCOM logo and main menu are specific to the Flatpak setup or can be reproduced in native Steam.
