Every now and then my system runs into following issue

When I right click on an item to select one of the options, the resultant box becomes unresponsive and just stays there, it overlays everything in the system, all apps, desktop everything. Box is not transparent because of which, I can not see the data it is overlaying.

Often it occurs in gedit and I have to close all my files and re-open just to get rid of the unresponsive box. But when it happens with other things like files explorer, I have to restart the system, shutting all my work down.

It is really disturbing my work, does anyone know what is the cause of this issue and how I can fix it, without having to restart system or apps.

There should be messages in your /var/log/Xorg.0.log file.

Obviously you can't get to them when the system is hung so run a terminal , click the title bar and set it to allways on top. then in the terminal run 

tail -f /var/log/Xorg.0.log

This will ensure you can see any log messages that might relate to the issue, if you can post it here we can solve it for you.

Another good source of info to run in a sticky window lack the last one is

journalctl -f

it contains more general log messages that might also explain it
