Processing Mode Native 8-bit CPU - Color shift below transparent clip

[MusicalBox]

What is your operating system? Windows 10 Home
What is your Shotcut version? 26.8.1

Track V1: Any clip.
Track V2: A clip with transparency. I the case below, just a Text clip with a transparent background. But a .mov clip with transparencies will have the same effect.

Exported project when Processing Mode is set to Native 8-bit CPU (check the background when the playhead reaches and leaves the text clip).

No problem when Processing Mode is set to Native 10-bit CPU

This is similar to the bug reported here (which was fixed) but in that case the brightness filter was involved:

Brightness on the track below a clip with transparency

What is your operating system? Window 10 What is your Shotcut version? 25.12.31 (Not sure if it was present on previous versions) Can you repeat the problem? If so, what are the steps? Steps Add clip on track V1 Apply a Brightness filter. Lower the level Add a clip with transparency on track V2 The brightness of the clip on V1 changes when the Playhead reaches the clip on V2.
