## I get some weird glitches/visual bug on _random program_!
Try launching it with a different TERM: $ TERM=xterm myapp. toe(1) will give
you a list of available terminals, but you’ll most likely switch between xterm,
st or st-256color. The default value for TERM can be changed in config.h
(TNAME).

## Why do images not work in st (in programs such as w3m)?
This is a terrible hack that overdraws an image on top of the terminal emulator
window. It also relies on a very specific way the terminal draws it's contents.
A more proper (but limited way) would be using sixels. Which st doesn't
support.
## 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.
