I've done "C-u C-x =" across different locations in the indentation until my fingers started aching, but no traces of :align-to display properties, or anything else that seemed suspicious to me. It always showed the expected font choice and size, i.e. all glyphs were reported to be of the same size. > Can you run this under a debugger and show the display elements in the > offending glyph_row?

I hence fail to figure out which buffer I'm looking at when the breakpoint in set_cursor_from_row triggers. Lldb does seem to find type information about the glyph_row though. Anything in the row I should be looking out for? FWIW, here are a few examples of gdb vs. lldb commands: https://developer.apple.com/library/archive/documentation/IDEs/Conceptual/gdb_to_lldb_transition_guide/document/lldb-command-examples.html#//apple_ref/doc/uid/TP40012917-CH3-SW1 Hoping to have helped, --alexander
