How to kill the GPU process:

1. Use https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer instead of normal task manager to see processes.
2. Search Mattermost.exe which has the parameter, --type=gpu-process.
3. Kill the process from the context menu.

I tested the artifact of CircleCI. The app is still running even when the GPU process is killed.
