Title kerning differs between Linux and Windows

Titles seem to render with different kerning between Linux and Windows.

Examples rendered on 22.08.1:

• Linux clip: https://files.kde.org/kdenlive/kdenlive-backcompat/results/test-22.08.1-appimage/compositions-wipe-20.12.1c.mp4
• Windows clip: https://files.kde.org/kdenlive/kdenlive-backcompat/results/test-22.08.1-win/compositions-wipe-20.12.1c.mp4

The "Wi" text seems to be closer together on Linux than on Windows.
