How to Reduce Large EKF Window

Suddenly, the EKF window got bigger.
The size of Alt + Space + R seems to be too large.

It’s the same even if you install the mission planner again.
Does anyone know how to reduce it to its original size?

delete the config.xml file from the documents/Mission Planner folder.

I have the same problem

Resolved!

What file is the config.xml file?
Do you have any related links to refer to?
