Blackmagic Native video capture issue when using @output_texture 1

I got an issue when capturing UHD video via a Blackmagic PCIe card using the device
- DeckLink Quad HDMI Recorder [Native]
The captured image is fine when using @output_texture 0 but it is half the width with artifacts when using @output_texture 1. See the screenshot attached.
Is there a solution to get the full width resolution for @output_texture 1 ?
The other Blackmagic devices
- Blackmagic WDM Capture
- Decklink Video Capture
are working in terms of texture resolution.
By the way, DeckLink Quad HDMI Recorder [Native]/ @output_texture 1 is the only setting where I am able to achieve 60fps as mentioned here:

Update: It does happen with FHD input source even worse, see attached screenshots

I do have there same king of problem but with a Recorder3G, simply using [jit.grab]'s help file.
Blackmagic DeckLinkAPI version: 14.2.0
OpenGL Version 4.1 Metal - 88.1, GLSL Version 4.10
Max8.5.7 or Max8.6.4, under macOS_14.6.1
Any solution since 2020?
This happens with the glcore graphics engine. With gl2 it does work fine.
