I have a big performance issues handling multiple projects in QtCreator 18.

This results in a lacky UI whenever I perform one of the following:

• A left click on a different project in the ProjectExplorer than before
• A right click on a different project in ProjectExplorer than before
• Selecting a file from another project than current via the open documents explorer
  This means, if I have 4 files open, 2 from Project A, 2 from Project B.
  Switching between the two files from Project A is no problem, but selecting one of Project B results in a short freeze and vice versa.

Attached is a GIF where I try to show this.
