Created attachment 165473 [details] project_seq-lose-transparency-bg SUMMARY If you close a sequence's tab (which has been added into another sequence's track), then save the project, close, reopen it, you'll find the sequence is rendered black-background (transparency lost) (watch the screen-record video I upload) STEPS TO REPRODUCE 1. Create project 2. Create title clip, with text, transparent background. Add it to Sequence 1 3. Create Sequence 2 4. Close Sequence 1 tab 5. Add a picture to Sequence 2 V1 6. Add Sequence 1 to Sequence 2 V2, above V1 picture (currently, the background of Sequence 1 is transparent) 7. Save, close, reopen OBSERVED RESULT After close and reopen, Sequence 1's background is rendered black in Sequence 2 EXPECTED RESULT Sequence 1's background should be rendered transparent in Sequence 2 SOFTWARE/OS VERSIONS Latest git master build (qt5) kdenlive-master-7360-linux-gcc-x86_64.AppImage ADDITIONAL INFORMATION 1. If you export video after reopen saved project, the exported video also have a wrong-rendered Sequence 1 black background 2. If you open Sequence 1's tab, then switch to Sequence 2, the background transparency comes back
