Mouse pointer sometimes becomes invisible for a while

[Matteo Dell'Amico]

Sometimes the mouse pointer becomes invisible for a while; then -- and I don't understand what triggers that -- it reappears. The mouse continues working -- mouseover and clicking works, so the only problem is that the pointer is invisible.

Happy to give you more details to help understand what's happening.

Running Ubuntu 16.04 on a Lenovo Thinkpad Twist.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.

Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.

Frankly I didn't remember this bug :) it's a machine in not using much anymore but I think at some point the problem stopped happening.

[Paul White (paulw2u)]

Matteo, thanks for your comment #3, I'm sorry I've only just seen it. Closing as probably fixed with an update sometime after reporting.
