Graphic bug when using Vulkan in Ape Escape (Spain) (Instructions of Ski Kidz Racing)

[edlink98]

Description

Here I report an error that is shown in the instructions of the Ski Kidz Racing mini game in the Ape Escape Spanish version. (Serial: SCES-02031) (Redump)
This graphic error appears when I use Beetle Psx HW with Vulkan and it is corrected when using OpenGL and Software. If I use the normal Beetle Psx it works perfectly.
In SwanStation the error appears when I use Vulkan, OpenGL, D3D11 and Software. (In Software mode the error is much more conspicuous.)

Expected behavior

While I was playing Ape Escape on the Beetle PSX HW core I was testing the minigames and Ski Kidz Racing and the instructions were showing an error on the right side of the screen.

Here I record what the error looks like using each Renderer (Vulkan, OpenGL, D3D11 and Software). I also did tests with SwanStation but I will report the error in their respective Repositories.

Bisect results

This started happening as soon as I noticed the error... I'm not sure how long it's been.
