Text timeline wont follow the transparent background color when Splitting

What is your operating system?
Linux 6.5.5-zen1-1-zen x86_64
LSB Version: n/a
Distributor ID: Arch
Description: Arch Linux
Release: rolling
Codename: n/a

What is your Shotcut version (see Help > About Shotcut)?
Shotcut version 23.09.29
from AUR, installed using yay shotcut

Can you repeat the problem? If so, what are the steps?
Steps to reproduce:

  1. Create new project
  2. Add a Color Timeline (Any color)
  3. Add a Text Timeline
  4. Extend the Text Timeline
  5. Split the Text Timeline
  6. Boom, black background on the 1st text timeline
    can be repeat again Step 5


My workaround or temporary solution is setting the background color alpha value to 1

Do you have Settings > GPU Effects turned on?
If so, this is a duplicate of 2 other reports with a workaround

Nope this is turned off, i have no gpu only igpu

I do not reproduce it using my Flatpak build, and I do not know what yay shotcut installs. More than likely it needs to upgrade MLT to the latest version (released same weekend as Shotcut 23.09 for a reason) as it has a fix for transparent color values getting saved wrong and then interpreted as black exactly as this bug describes:


For now i im using the transparent alpha value “1” as a workaround

sometimes I forgot to set the workaround and posted the video on public
this is now very annoying, i hope this will fix soon
