If you wish to run kate (an advanced text editor for KDE) or kile (an integrated LaTeX environment) on coxeter (say, on a file called file.tex) then it is best to use a command line of the form:
kate --graphicssystem native file.tex
and
kile --graphicssystem native file.tex
The latest major update to the KDE graphics system has caused those programs to run quite slowly without those options.
