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 the same kind 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.

I thought this got sorted out but I'll take another look.

Will there be a fix for Max8 or only for Max9?

If there is a Max 8 update, the fix will be in there. However I can also throw up a Jitter Tools update on the Package Manager that will fix this. Just wanted to get some verifications that the fix works and doesn't create other side effects. I'll try and get that up this week and will notify here when it is.
