The "Graphics Device Unsupported" warning screen never appears when improved transparency is turned on with a graphics device on the warnlist

The Bug:

The "Graphics Device Unsupported" warning screen never appears when improved transparency is turned on with a graphics device on the warnlist.

The game keeps a list of graphics devices it does not support, and shows the "Graphics Device Unsupported" screen when a player on such a device turns on improved transparency. However, this said screen never appears, and players on an unsupported device are not warned before turning on improved transparency.

Steps to Reproduce:

1. Navigate to your video settings and turn the “Improved Transparency” option off.

2. Download and enable the attached resource pack.

3. Navigate to your video settings once again and turn the “Improved Transparency” option on.

4. Observe if the "Graphics Device Unsupported" screen appears.

Observed Behavior:

The "Graphics Device Unsupported" screen doesn’t open.

Expected Behavior:

The "Graphics Device Unsupported" screen would open.
