Yes, works much better now. Still a bit strange that the position values are not absolute like they normally are. A translation of 1 = 100px. But that’s okay, I just multiply by the texture size and its fine that way and works even if the texture size changes.
Thank you for pointing this out! Of course the right settings were missing.
In the upcoming preview build ( > 2022.5.0-577 ), there will be two nodes: Insert for pixelpace and Insert (UV) for (0,1) space. Nodes are not Experimentral anymore and are moved into the Mixer category.
