Re: [NTG-context] Backgrounds has changed in latest lmtx

21 Oct 2022

      Hi Thomas,

Your example does indeed show the issue I had reported on with Simpleslides: the backgrounds of the slides are not as expected.
So it seems that beginning with version 2022-10-15 something has changed with Metapost or the background mechanism.

Best regards: Otared

Hi everybody,
With the latest lmtx, my page backgrounds don’t work any more. I think Otared mentioned that the simpleslides module is having problems. I’m trying to figure out what is happening, but I don’t see any warnings or errors, just unexpected results (which is not a good thing). I’m starting with the fundamentals. Here is a fairly minimal example: compile with context --luatex to see the expected result and with lmtx to see what is wrong.
All best
Thomas
