Nope. They were different tress I was barking at. This is slightly more
conclusive that is the glyph rendering that is producing too much load.

First can you quickly test master as I tweaked placement of glyph operations.

Then check

diff --git a/src/sna/sna_glyphs.c b/src/sna/sna_glyphs.c
index e8d92b8..5350eb0 100644
--- a/src/sna/sna_glyphs.c

and then
