if it crashes a startup error will be shown via `xmessage`, there will
be not window manager (most likely) at that point and many things will
not work as expected.
ksmserver cannot be restarted for example, drkonqi is not option either
because attempting to report a bug will open a browser but the backtrace
cannot be copied (the browser window will be on top of any other window
if it launches with no way to switch to the drkonqi window), etc.
in other words - the best thing that can be done is log the backtrace to
the system log (the ksmserver debug area has to be configured for that)

if Xrender is not found a fatal message will be issued by the top-level
CMakeLists file because it is required by KWin compositor for example

the effect is very much bound to the window manager (KWin) because if
applications require attention (such as confirmation to cancel any
pending changes) their window or any dialog they pop may have to be
raised, will have to be focused and not be grayed out
