+## 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.

|
|
|
+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.
