Change the mesa/graphics version

The Steam snap relies on the gaming-graphics-core24 snap for graphics packages. You can verify this by running snap connections steam.

You may switch gaming-graphics-core24 to a different channel to use different versions of mesa and other graphics libraries.

Currently, the channels are:

• kisak-turtle (most stable)

• kisak-fresh (new, but stable)

• oibaf-latest (bleeding edge)

Switch between them with the following command:

snap refresh gaming-graphics-core24 --channel <channel>

To find what version of the gaming-graphics-core24 Snap you have, use the following command:

snap info gaming-graphics-core24
