From: Iñigo Serna <inigoserna <at> gmx.com> To: bug-gnu-emacs <at> gnu.org Subject: 31.0.50; Rendering HTML email is very slow since commit #eab14d68b2e72b9a6b8b0cc67c9667c2bfbed4f5 Date: Mon, 21 Apr 2025 10:34:01 +0200
Hi,
Since a few weeks ago I'm noting that HTML emails rendering is
very slow,
f.e. from 1 second to 5-6 seconds.
I compile Emacs with PGTK and Native Compilation every week on
GNU/Linux Fedora 41/42, and use mu4e to read emails.
More info of my compilation flags below.
Today I got some free time and proceed to profile the issue, it
showed
~10x more time in function 'shr-render-td-1' vs emacs v30.1.
As this function is not changed since time ago I've bisected the
problem,
which showed that the commit
#eab14d68b2e72b9a6b8b0cc67c9667c2bfbed4f5
was the culprit:
[machine] /h/_/l/d/emacs.bug > git bisect good
eab14d68b2e72b9a6b8b0cc67c9667c2bfbed4f5 is the first bad
commit
commit eab14d68b2e72b9a6b8b0cc67c9667c2bfbed4f5
Author: Gerd Möllmann <gerd.moellmann <at> gmail.com>
Make sure to initialize glyph::frame to NULL (bug#77039)
* src/dispnew.c (adjust_glyph_matrix): Clear glyph
memory when
enlarging window-system window glyph matrices.
src/dispnew.c | 3 ++-
1 file changed, 2 insertions(+), 1 deletion(-)
If I comment out the two lines added in this commit, problem
disappears.
I've read bug #77039 comment but it's way off my understanding.
But looking deeper into the problem, it is related with my own
theme,
which hides mode-line of non-active windows by setting its height
to a
small value:
(mode-line-inactive ((((type tty)) (:background "#222222"
:foreground
,elms-fg :height 0.1))
(((type graphic)) (:background ,elms-bg
:foreground ,elms-fg :height 0.1))))
If remove that height attribute (or set it to a bigger value such
as
0.6) the issue disappears.
Thanks,
