Arch Linux

Two rendering issues present in the mupdf 1.13.0-1, which might be unrelated:
1. mupdf fails to render the image at the top of the page in the attached file R042018_Lewisham-P13.pdf, and outputs the following to the terminal:
"""error: Cannot convert between incompatible pixmaps
warning: Ignoring error during interpretation
error: Cannot convert between incompatible pixmaps
warning: Ignoring error during interpretation
mupdf: warning: Errors found on page. Page rendering may be incomplete."""
2. There are coloured rendering artifacts, which look a bit like the effect of rendering the R,G,B layers in slightly different positions. These artifacts, when they occur, affect the entirety of the page, although in a variable fashion, and the artificts also vary when changing the zoom level. This issue is present on pages 1 and 3 of the attached file citi-5-jan-2018.pdf; a screenshot of mupdf's display of page 1 is also attached. The issue appears to be triggered by the shaded columns containing the 0720 bus (on page 1) and 0556/0602/0652/0702 buses (on page 3); this pattern holds across a number of other timetables too.

I have downgraded mupdf to 1.12.0-2 and confirmed that these issues do not appear there. I have also been unable to reproduce these issues in various self-compiled versions of the code - these versions being the linux .tar.gz download on the mupdf website, the latest git commit (709b4b) as of earlier today, and the git commit tagged 1.13.0.
