CMake settings unresponsive with long "CMake options" field

Hi,

I have a noticed that the UI becomes unresponsive when I open my CMake settings. Finally I seem to have found that it is all caused by a rather long "CMake options". It does not fit in the edit control and that seems to cause the UI to not be updated anymore. I can leave the settings with "Cancel" or "Ok".

What's really interesting is that when I resize the settings dialog such that the entire line does fit, the UI shows no slowness at all.

Reload CMake project on editing CMakeLists.txt is unchecked.

The "Cmake options" is: -DENABLE_TESTING=TRUE -DBUILD_SHARED_LIBS=TRUE -G "Ninja" -DCMAKE_TOOLCHAIN_FILE=../../native/cpp/cmake/toolchains/gcc-10.cmake

Has anyone else noticed this behaviour?

2020.2.4 by the way.
