1. IMHO, it should compare the cached display string with == instead of != (though != has been there since the old kdelibs, but it just doesn't look correct to me, what's the point of assign dpy = mCached_dpy when dpy_str != XDisplayString(dpy)? And what's the point use == in one place and != in other two places? ).
2. it might free the cached connection without setting mCached.conn back to nullptr, which could lead to double free or freeze when system logout.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch refactor the code a little bit with a helper function to update the cached connection instead of duplicate the same logic everywhere. getXCBConnection() will make sure the returned connection is error-free, reuse the cached connection if possible, and update the cached connection if needed.</p></pre>
