Gedit hangs while searching in large file

[jolo]

When I did a search in Gedit with a large text file (about 101 KB), the editor hangs and used high CPU load.
When I shut down the application, a dialog box appears: The Window "history.log (/var/log/apt) - gedit" is not respondig. This dialog box is attached.

Also the top output is attached.

Status changed to 'Confirmed' because the bug affects multiple users.

THIS IS REALLY ANNOYING, the immediatly starting search function stalls the program in long files (e.g. I want to search for "def", it stalls the program with searching all d's and so on (gedit gets greyed out) for a minute)
You can add an option to preferences, if user wants immediate search for every letter you enter.
Please fix this asap.

Workaround: always use the replace dialogue box for searching text.

The upstream bug has a proposed patch:

This is still present in 16.04 LTS. Disable on-key event, instead make Search button (enter) to start the actual search after user have finished string input!

It seems to be notable in html files when highlighting is on.

the same with Ubuntu v. 16.04 -> https://bugs.launchpad.net/ubuntu/+source/gedit/+bug/1862924
