A guide to running TouchDesigner under Proton 10 (GE-Proton 10, Proton-CachyOS, etc.) on Linux using umu-launcher or faugus-launcher, including Spout2PW for video output to OBS.
As of GE-Proton 10-32 and TouchDesigner 2025.32460. This may be fixed in future Proton or TouchDesigner releases.
TouchDesigner runs fine under Proton 9 (e.g. GE-Proton9-27) but hangs on Proton 10. It shows the loading window for the default project, the loading animation freezes, and it stays unresponsive until killed.
