is there a way to disable interactive PDF features and generate just a simple searchable PDF like in the 6.x version? The main reason is that the size of the interactive PDF is too large for complex boards and it is hard to copy&search references.
Additional to my workaround above (and the solution from @maui) there is the possibility to use the “Print” function and use a virtual pdf-printer driver.
In the past “Print” has created artifacts compared with “Plot”.
Passing the KiCad pdf output through a 3rd part program to flatten the pdf is also adding a level of possible errors.
Changing the behaviour so drastically in V7, without serious discussion was a big mistake.
Apart from the size and exposed fields, the pdf can be modified by the viewer
