[Support] Library Stutter/Hangs after exiting games - Radeon 9060 XT / LG C9 OLED

Bazzite
1

Hey everyone,

I’m running into a persistent UI issue in Game Mode and I’m curious if anyone with a similar AMD/OLED setup has found a workaround.

The Problem

Every time I exit a game and return to my library in gamescope(gamemode), the interface becomes extremely laggy. When I try to scroll, the UI hangs/stutters for a split second before catching up, and hangs again, and catchs up, … . It feels like the interface is struggling to re-assert itself after the game process closes.

System Specs

  • GPU: Radeon 9060 XT (16GB)

  • CPU: Intel Core i14600

  • RAM: 16GB

  • Display: LG C9 OLED (Connected via DisplayPort to HDMI adapter)

  • Controller: Xbox Controller via Bluetooth

  • Bazzite Version: Latest Stable Build

Important Context

  • Display Setup: Since I’m using a DP-to-HDMI adapter to connect the LG C9, I’m wondering if this is a refresh rate switching/handshake delay occurring when Gamescope transitions from the game’s frame buffer back to the UI.

  • Controller: Using an Xbox controller over BT (I’ve heard rumors of BT polling causing stutters, but it only happens in the library).

  • UI: Im using two themes, one for round cards, and other to fullscreen image when i select a game.

  • OC: Im doing a OC and undervolt in lact.

What I’ve Tried

  • Verified “GPU accelerated rendering” is enabled in Steam settings.

  • Cleared Steam Web Browser cache.

  • Ran ujust update to ensure I’m on the latest stable bits.

Is there a specific Gamescope flag or an AMD-specific power profile I should be using for the 9060 XT? It almost feels like the GPU clocks are dropping too low the moment the game exits, leaving the UI to crawl.

Thanks for any help!
