--- Comment #33 from Andrey <meges...@efenstor.net> --- Okay, here is the minimalistic project which I think exposes the same problem which I was struggling with when working on my music video: https://disk.yandex.ru/d/aqkbAfXXJv83aA There are 4 versions of the project (crash_test.kdenlive, crash_test2.kdenlive, etc.), from the most stable to the (probably) most unstable. Summarizing the test conditions: the system configuration is Debian 10 (stable), GNOME with Wayland, AMD Ryzen 7 2700 8-Core CPU, 32 GB of RAM, MSI Radeon RX 5600 XT video card, HiDPI 4K monitor. Kdenlive is the Flatpak version, installed from Flathub into user space (not Super User/system-wide). QT backend is set to "xcb" via QT_QPA_PLATFORM=xcb added to org.kde.kdenlive env overrides. Rendering is done with Parallel Processing set to 15, setting it to 1 seemingly eliminates the problem. Crashes are starting to happen when I add several of Vignette and/or Cairo Gradient effects alongside with other complex effects (Video Noise Generator, Deband, LUT). When rendering crash_test3.kdenlive the crash can be provoked by dragging the timeline cursor back and forth and over the end of the project in the background while rendering the job. -- You are receiving this mail because: You are watching all bug changes.
