Scrambled VR desktop on Linux

I am having trouble getting VR to work on Linux (Fedora 42). I'm using ALVR Dashboard streamer v20.14.1 and the latest TestFlight version on Apple Vision Pro with Vision OS 26. When I connect the "Valley" scene looks great and my PSVR2 controllers even work great. However, I am not taken to the Steam VR Home like on Windows. When I press the "Options" button to view the Dashboard, it looks scrambled and artifacted (see screenshot). This happens no matter when encoder I choose, H.264, HEVC, or AV1 - all result in the same scrambled dashboard. <img width="1280" height="720" alt="Image" src="https://github.com/user-attachments/assets/42003ab1-bbcf-4805-a34d-1bfbde6f55ba" /> The logs don't have anything helpful in them for me, but I've included them below. ``` 22:52:12.429 [INFO] Driver name: radv 22:52:12.429 [INFO] Driver name: radv 22:52:12.429 [WARNING] For functioning VR you need to put the following line into SteamVR's launch options and restart it: DRI_PRIME=1 /home/dutch/.local/share/Steam/steamapps/common/SteamVR/bin/vrmonitor.sh %command% 22:52:12.429 [WARNING] And this similar line to the launch options of ALL games that you're trying to launch from steam: DRI_PRIME=1 %command% 22:52:12.432 [INFO] GPU Encoder vendor: Mesa Gallium driver 25.1.7 for AMD Radeon RX 9070 XT (radeonsi, gfx1201, LLVM 20.1.8, DRM 3.64, 6.16.5-200.fc42.x86_64) 22:52:12.434 [INFO] GPU Encoder vendor: Mesa Gallium driver 25.1.7 for AMD Radeon RX 9070 XT (radeonsi, gfx1201, LLVM 20.1.8, DRM 3.64, 6.16.5-200.fc42.x86_64) 22:52:14.419 [INFO] Server connected 22:53:20.063 [INFO] Initial socket buffer size: send: 87040B, recv: 131072B 22:53:20.093 [INFO] Initial socket buffer size: send: 212992B, recv: 212992B 22:53:20.093 [INFO] Set socket send buffer succeeded: 425984 22:53:20.093 [INFO] Set socket recv buffer succeeded: 425984 22:53:20.094 [INFO] Render Target: 4288 2048 22:53:20.094 [INFO] Refresh Rate: 90 22:53:20.107 [INFO] CEncoder::Run 22:53:20.107 [INFO] CEncoder Listening 22:53:20.199 [INFO] CEncoder client connected, pid 23779, cmdline /home/dutch/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor 22:53:20.223 [INFO] Using Vulkan device AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO) 22:53:20.223 [INFO] Using device path /dev/dri/renderD129 22:53:20.224 [INFO] FrameRender: Input size 4288x2048 22:53:20.225 [INFO] FrameRender: Output size 2560x1088 22:53:20.244 [INFO] Using VAAPI encoder 22:53:27.305 [WARNING] Desync detected.

I read through the troubleshooting guides and have not found anything that helps, either.
