This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Whenever you do anything in NetBeans, it will write to the uigestures file in the NetBeans log directory. If you run on an OS that provides the user with a personal RAM based directory (e g $XDG_RUNTIME_DIR) it would be nice if you could tell NetBeans to create its log directory there instead of in the profile directorty. You can do it yourself with a script, see https://www.grim.se/guide/nblog-tmpfs
