Created attachment 176442 [details] Two-line subtitle SUMMARY Kdenlive has made some very welcome changes to its subtitling feature. What you see in the image attached to this report are my suggestions for improving it further. STEPS TO REPRODUCE 1. Create a subtitle 2. In Subtitle Style Editor, Background choose "Box as Outline" 3. Change Outline color to black with Alpha Channel setting at 150 OBSERVED RESULT 1. When using two or more lines of text with a semi-transparent background - "Box as outline" with Alpha Channel set to a value of 150 - what happens now is the box outlines of the subtitle are not uniform, but the part where they meet gets darker as the box above overlaps the one with text below. In the image attached on the right I have highlighted the dark line in yellow on Kdenlive's monitor. 2. In the Subtitle Style Editor when I click the "Show Preview" button, I only see the first line of my subtitle even though it contains two in this case. EXPECTED RESULT 1. Make the outline color uniform if background color of the outline is semi-transparent and don't allow boxes to overlap if there is only one subtitle with two or more lines of text. 2. Preview multiple lines of text as in the subtitle.

Thank you for the feedback. The new subtitle editor comes with version 24.12.0. Let’s see what else we have to adjust. I updated the bug title a bit.
Please see the comments in https://bugs.kde.org/show_bug.cgi?id=461202 about the overlapping border issue and what can/can't be done about that. Re the separate preview issue also reported here. In the new code that should be landing soon there is no longer any "show preview" needed for the style editor - changes to any style immediately propagate to clips using it in the timeline, so you can 'preview' any clip you like just by moving the timeline cursor to it while editing a style. So I won't split this report and keep it open just for that since it's already 'fixed' in my dev tree and should land in an official release Soon. *** This bug has been marked as a duplicate of bug 461202 ***
