Text overlay shifts levels slightly #1517

Shotcut 24.01.28 The fading out of the title in the attached sample makes the luma shift by 1 or 2 steps down, see the waveform monitor. Or better: the addition of the title shifts the luma 1 or 2 steps up. Changing opacity and/or the RGB value of the text (254,254,254) doesn't have an effect. Am I missing something? The text is added on a separate video track.

Edit: It looks like the appearance/disappearance of the text would trigger a change between limited range<->full range. (The video is limited range).
