Thank you for reporting. Confirmed as you descript. Thanks for your report. In fact this regression was caused by a change in MLT, our video backend. Svg can be handled by 2 different plugins: -qimage using Qt's svg rendering -pixbuf using GTK's rendering. While Qt's support for image formats generally seems better, SVG support is still very limited. This commit in MLT switched from pixbuf to qimage by default causing the regression: https://github.com/mltframework/mlt/commit/7bf5da86d4f2f8f83f45b9809fb061cbfdd97906#diff-3618679c822f96781a092c5f0114ccfc I will try to ask if there was a reason for this switch for SVG or if it can be reverted... Hello, Very recently MLT switched the default module used for image rendering (from FFmpeg to Qt I believe). This is probably the problem. The change is in loader.dict text file, that can be copied from one install to the other to check? Thank you for the information. I am using AppImage executables, one for each version, so I can't change my installation files. I can read them, though... As you pointed out, I also have qimage set to default over pixbuf: *.svg=qimage,pixbuf *** Bug 415440 has been marked as a duplicate of this bug. *** *** Bug 421168 has been marked as a duplicate of this bug. *** *** Bug 405249 has been marked as a duplicate of this bug. *** |
Created attachment 127931 [details] SVG image with shadow SUMMARY I have a project created in 20.04.0 version, with the attached SVG image. It has a shadow layer, with semi-transparent gray color. I've used it in another project made with 19.12.3 some days before the fresh project. I also rendered this older project with 19.12.3, and in it the shadow-part of my image is visible. But rendering my new project with 20.04.0 only renders the red shape itself, without the semi-transparent shadow part. Interestingly, after I load the new project into the old version, and do the rendering, the shadow is visible again. STEPS TO REPRODUCE 1. Insert some background in a new project on V1 track, for example white color. 2. Place the attached image above it, on V2 track (default 5 seconds duration is enough) 3. Render the video and check it OBSERVED RESULT My video shows the red shape, but not the shadows. EXPECTED RESULT My video should show every part of my image, the shape and also the shadow.
