Thank you for taking the time to report this bug and helping to make Ubuntu better.

A photo (or video) of your issue may have helped highlight your issue. Providing a link to where it can be seen would be welcome too.

Does the issue occur when you're using other OSes (a live system if this is your only installed OS); ie. have you ruled out hardware issues?

Has it started to occur after a recent update?

The more details you provide, the greater the chance of the cause being detected & thus fixed.

A Support site maybe more useful if help in dealing with it is wanted, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709
