The bug
The background (options_background) of the "select resource pack" screen is not aligned correctly, under the two dark panels. This happens without any resource pack on.
With another resource pack this is however more easily noticeable, images are attached.
How to reproduce
From the main menu, open Options
Watch the background closely below the "Done" button
Click the "Resource packs" button
❌ see how the background shifts

On 58.png and 61.png you can see that on the top and bottom of the darkened the texture, although repeated as you state, is not quite aligned correctly. I have attached 59.png and 60.png to show that the background texture repeats properly on all of the other menus.
This was somewhat fixed in 1.20.2-1.20.4 and is now fully fixed in snapshot 1.20.5 Pre-Release 1 due to the removal of the dirt background
I think it's works as intended. The background is getting repeated and ends until the window width/height.
