3. Run setup/Linux/createPackages.sh

4. Run AppDir/usr/bin/sourcetrail

5. Click Recent Projects: - tictactoe_cpp

6. Click Edit - Preferences...

7. UI freeze

8. If I wait for several minutes the preferences window will eventually render

The root of this issue is the following bug in Boost.Process https://github.com/boostorg/process/issues/69.

wait_for does not return when the process exits during the waiting time.

On my Linux machine, the "Edit" interface invokes the 2 compilers "clang" and "gcc", which leads to the window freezing for the full timeout of 2x30s. Thankfully one doesn't have to reconfigure too often :wink:
