Univention Bugzilla – Bug 47985
High browser CPU usage on the search page of the users/user module
Last modified: 2019-07-01 14:45:47 CEST
For the users/user module the detail page is pre-created so that opening a user object is faster. But before a user object is loaded the detail page shows a standby animation. This will cause a standby animation to constantly run in the background when the search page of the user/user module is open. (The tab of the users/user module does not even have to be selected. The users/user module just has to have the search page selected.) The StandbyWidget is not really performant and performs dom manipulations on a high frequency which causes the CPU usage of the browser to rise.

I cannot reproduce the high browser usage. But it does not break anything, the spinner is gone from the DOM and users reported that it actually improved for them. So VERIFIED
