200% scaling, everything is displayed wrong in Project Monitor

## SUMMARY
When Display Scaling setting is not 100%, Kdenlive's Project Monitor showing item's position and scaling is different than the output file.

As shown in the attached screenshots, in 100% scaling, Project Monitor display it correctly, while 200% does not,

Proxy clips is enabled (320pixels)

This issue:
1)  Can be found before 24.08, I cannot trace back which version doesn't have this  problem.
I can only assume it's been around.

I didn't report that because I wasn't really into kdenlive back then.

2) Project resolution doesn't matter, I tried 1920x1080, 1280x720, also has position issue.
