Qt Creator mouse cursor disappears after pressing ctrl-s to save a document

  • I just noticed it doing it today. I found a bug from 2016 that did something similar. I am running a dark theme that is built in to Qt Creator.

    To reproduce:
    Press ctrl-s to save a document while in the editor. The mouse cursor will disappear. I swear this didn't do this earlier this week. I had not updated Qt Creator, I did an update on it in case it was an issue that was fixed. The update did not fix. Running Qt Creator 4.10.2 in Ubuntu 18.04 Linux.

  • Rebooting computer fixed. It was not enough to restart Qt Creator, I had to reboot. I might have been fixed if I just logged out, I don't know. Sounds like a X11 issue.
