This fixes a
std::future_error: "Promise already satisfied"crash that I was experiencing running on an RTX 3080ti. I believe it may be something to do with the CUDA context creation being much slower than for VA-API (which works without issue on my setup).To reproduce, launch any app from Moonlight (I used Test Ball) on a host with the following environment
GPU: NVIDIA GeForce RTX 3080 Ti (GA102 / Ampere)
Driver: 595.71.05 (host)
Host OS: Fedora CoreOS 43 (uCore
ucore-hci:stable-nvidia), kernel 6.19.12-200.fc43Container runtime:: podman, systemd quadlet setup
