Hi bug-gnu-emacs,
If I create a file temp.txt containing the following:
-*- prettify-symbols-alist: (("R_PO" 8477 (Br . cl) 8804)); -*-
!!! R_PO !!!
and run ‘emacs-24.5 -Q temp.txt -f prettify-symbols-mode’, I observe a
surprising display bug: when I move the point across the second line, as soon
as the point reaches the blank space after “R_PO”, I see a second ℝ displayed
instead of the third “!”.
Concretely, the line looks like “!!! ℝ≤ !!!” until I reach the second blank,
and then it changes to “!!ℝ ℝ≤ !!!”. Resizing the window fixes the issue until
the next cursor blink. Additionally, when the point is on R_PO, the point
disappears — and taking a screenshot makes the prettified R_PO (ℝ≤) disappear,
too (?!).
Is this a known issue? Can anyone else reproduce it? I have attached a few
pictures (all of them show the same buffer text) — let me know if I can provide
any other info!
Cheers,
Clément.
