    Description

      My app was build on macOS 10.14.6, with Qt 5.15.2. When I run it on macOS big sur. The text in QLabel is missing space char after a comma or period. It is very easy to reproduce. Just create a dummy widget application project, put a QLabel on it, set its text to:

      "This is a test. This is a test"

      The displayed text on Big Sur looks like this:

      "This is a test.This is a test". 

      On macOS 10.15.x it displays correctly.

      It happens to all my QLabels, which is a disaster Anyone noticed the bug?

      -------

      Update: Tested building under macOS Big Sur and the latest XCode. Same issue. 

      Update 2: Source files uploaded
