I can confirm that it doesn't crash anymore.
And the performance improvement is really great; I've been able to
scroll down the whole etc/NEWS buffer with the redisplay keeping the
pace and not a single undesired recenter in sight...
BTW, one of those questions about weird font selection choices by the
font backend:
In etc/HELLO there are two instances of U+2200 (FOR ALL). The newest
release of DejaVu (2.26) added a glyph for that codepoint to DejaVu
Sans Mono, which I use as default font.
Now the weird thing is, the first FOR ALL in etc/HELLO is shown as
character: ∀ (8704, #o21000, #x2200)
preferred charset: unicode (Unicode (ISO10646))
code point: 0x2200
syntax: . which means: punctuation
category: h:Korean j:Japanese
buffer code: #xE2 #x88 #x80
file code: ESC #x24 #x42 #x22 #x4F (encoded by coding system
iso-2022-7bit-dos)
display: by this font (glyph code)
uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso10646-1 (#x7A2)
while the second one is
character: ∀ (8704, #o21000, #x2200)
preferred charset: unicode (Unicode (ISO10646))
code point: 0x2200
syntax: . which means: punctuation
category: h:Korean j:Japanese
buffer code: #xE2 #x88 #x80
file code: ESC #x24 #x42 #x22 #x4F (encoded by coding system
iso-2022-7bit-dos)
display: by this font (glyph code)
uniscribe:-outline-MS
Mincho-normal-normal-normal-mono-13-*-*-*-c-*-jisx0208*-* (#x421)
Shouldn't it use DejaVu Sans Mono for both?
