Latest nightly (2.7-Vulkan 4249e39) has graphics issues in Mario Kart 64 (GLideN64), stable release (2.6-Vulkan 5d2ac21) works

[AndBu]

After updating the latest Mupen64Plus-Next core in retroarch (core version 2.7-Vulkan 4249e39), the HUD was no longer showing correctly in Mario Kart 64 in a two-player game (single player worked but I only tried for a minute or so). No mini map was shown and no Items were shown. RDP was GLideN64.

Steps to reproduce:

1. Fresh download of retroarch Windows x64
2. Update Mupen64Plus-Next core via online update (core version 2.7-Vulkan 4249e39)
3. Change GlideN64 config "Less accurate blending mode" from OFF to ON to get rid of black boxes in UI as described here
4. Run a two-player Mario Kart 64 game e.g. battle on donut (USA rom)
5. Observe the HUD not showing

Probably someone already noticed, but I am putting this here just in case.

Switching back to stable (2.6-Vulkan 5d2ac21) as included in retroarch v1.19.1 fixes the issue.

P.s. I feel like there should be an option to only download the latest stable cores when updating and it should be the default or the update functionality should come with a big fat warning that you are actually updating to nightly builds. This issue took me a while to track down because I was looking in the entirely wrong place (thought it must be a settings issue).
