Linux Mint 21.2 Cinnamon
How to recreate the problem:
I’m creating text:simple (this problem also exists in text:rich), I cut the track into several pieces and change the text in each. During playback, the text changes normally, as it should be. But if I create a path under the text with color, the text will stop changing, the same thing if the project is rendered. This issue is only detected when GPU Effects mode is enabled. I’m posting a video of what I mean. This problem exists in any version of Shotcut that can work with GPU effects.
