Description

Shotcut Windows 10 64bit - version independend (presumably)

Observed in the Text: Simple filter - didn't check others

Steps to reproduce:
1.) Create a 1080p project with a clip and apply Text: Simple filter.
2.) Enter 10 lines of text
3.) Turn on preview scaling 360p
Result:
Last line of text is shifted up by more than one line.

Note: there are severeal other minor inaccuracies with preview scaling in various filters - however nothing neraly that obvious AFAIK.

Research direction

Reproduce the issue in a 1080p project using the Text: Simple filter, ten lines of text, and 360p preview scaling. Trace the preview-scaling path for multiline text and verify that the final line remains aligned with the unscaled preview; also check whether the other noted filter inaccuracies are related.
