-## Why do images not work in st using the w3m image hack?
-
-w3mimg uses a hack that draws an image on top of the terminal emulator Drawable

-## BadLength X error in Xft when trying to render emoji
-
-Xft makes st crash when rendering color emojis with the following error:
-
-"X Error of failed request:  BadLength (poly request too large or internal Xlib length error)"
-  Major opcode of failed request:  139 (RENDER)
-  Minor opcode of failed request:  20 (RenderAddGlyphs)
-  Serial number of failed request: 1595
-  Current serial number in output stream:  1818"
-
-This is a known bug in Xft (not st) which happens on some platforms and
-combination of particular fonts and fontconfig settings.
-
-See also:
-https://gitlab.freedesktop.org/xorg/lib/libxft/issues/6
-https://bugs.freedesktop.org/show_bug.cgi?id=107534
-https://bugzilla.redhat.com/show_bug.cgi?id=1498269
-
-The solution is to remove color emoji fonts or disable this in the fontconfig
-XML configuration.  As an ugly workaround (which may work only on newer
-fontconfig versions (FC_COLOR)), the following code can be used to mask color
-fonts:
-
-	FcPatternAddBool(fcpattern, FC_COLOR, FcFalse);
-
-Please don't bother reporting this bug to st, but notify the upstream Xft
-developers about fixing this bug.
-
-As of 2022-09-05 this now seems to be finally fixed in libXft 2.3.5:
-https://gitlab.freedesktop.org/xorg/lib/libxft/-/blob/libXft-2.3.5/NEWS
