Try launching it with a different TERM: $ TERM=xterm myapp. toe(1) will give

## 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
window. The hack relies on the terminal to use a single buffer to draw its
contents directly.
st uses double-buffered drawing so the image is quickly replaced and may show a
short flicker effect.
Below is a patch example to change st double-buffering to a single Drawable
buffer.

## 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.
