SUMMARY:

After configuring a Resource Pack under Global Resources, then exiting and restarting the game, the settings are not retained.

STEPS TO REPRODUCE:

1. Download and Activate the VanillaBDcraft Resource pack.
2. Under Global Resources, configure the resource pack to load at less-than-default resolution.
3. Exit settings.

1. Start playing a world to verify that the resource pack loads.

1. Exit the game (I use the (X) button and find the "Quit" option in the game's context menu)

1. Start the game up and verify whether the settings were saved.
