There are quite a lot of details missing from the bug report.  In the
first place, what font is Emacs using?  Type

  M-x describe-face RET default RET

and show the entire output.

Also, are you specifying the font in your Emacs init file (via face
customization), or in .Xresources?  And is Emacs compiled with GSettings
and -lfreetype support (these should be reported in the messages near
the output of ./configure)?
