    First off, make sure you have applied all the updates using yast
    online update. From the patch file xorg-x11-libs-52303:

    Longdescription.english:
    Fix font display problems showing up with internationalized
    applications using legacy toolkits like gtk1, Athena
    Widgets, etc., e.g. xmms. This happened when using
    languages like Czech, Russian, Greek and others. Depending
    on which fonts are installed the previous update could
    result in 100% CPU usage by the Xserver when starting such
    applications. This is fixed now.
    Hsilgne.noitpircsedgnol:

    After doing that, you might consider switching your window manager to
    something which is more efficient like fvwm2 (my favorite and very,
    very fast and exceptionally powerful when configured correctly.)
