Description

It seems that the halign property of the composite transition is not honored when the geometry causes a qtext track to be reduced in size to fit the bounding rectangle. The resized track always gets a centered alignment.

This melt command reproduces the issue: https://pastebin.com/5yz4N3qC

The same happens with the pango producer as well.

Any means to have a text track aligned to left even when it gets resized?

Thanks!

Research direction

Start by running the linked melt command and examining the composite transition with the qtext and pango producers. Trace how the resized text track handles halign; done means left alignment is preserved when the track is reduced to fit the bounding rectangle.
