For me Emacs flickers by just writing or scrolling around. It is quite
annoying to work with unless I activate the tearing prevention feature
on KDE's settings, which I'll like to avoid because it is buggy.

I'm eager to try your code, but `patch' complains about

address@hidden:~/dev/emacs/stable/source$ patch -p 1 < ~/p.patch 
patching file configure.ac
patching file src/Makefile.in
patch: **** malformed patch at line 60: $(LIBSELINUX_LIBS) \


And indeed, the patch shows:

    $(LIBXML2_LIBS) $(LIBGPM) $(LIBS_SYSTEM) $(CAIRO_LIBS) \
    $(LIBS_TERMCAP) $(GETLOADAVG_LIBS) $(SETTINGS_LIBS)
$(LIBSELINUX_LIBS) \
    $(FREETYPE_LIBS) $(FONTCONFIG_LIBS) $(LIBOTF_LIBS) $(M17N_FLT_LIBS) \


It looks like the typical text wrap problem. There are more cases like
this.

Could you send the patch as an attachment, please?
