Gleidoscope screensaver crash - cannot change

Hello all

I have just installed 11.1 and was flicking through the screensavers (as you do!) and reached “Gleidoscope” - The system locked up and I had to hard reset.

Now, when I select the screensaver option, the system hangs in the same way and I cannot change away from that screensaver!

I would appreciate any advice.

Nevermind. This seems to fixed in an update!
