The Bug:

The right side of incompatible resource or data packs isn't rendered correctly when the scroll bar is present.

1. Download multiple incompatible resource packs and place them in your resource packs folder.
2. When the scroll bar is present, select on of the incompatible resource packs.
3. Observe the right side of the selected incompatible resource pack.

Observed Behavior:

The right side of the white outline of incompatible resource/data packs isn't rendered. The red background on the right side also doesn't have any padding.

Expected Behavior:

The right side of the white outline of incompatible resource/data packs would be rendered. The red background on the right side would also have padding.
