SUMMARY Monitors don't display the whole image, as if the zoom factor was set to 100%. Things go back to normal (image scaled to fit) if Waveform/Histogram/etc. (windows right to the monitors) are disabled in the "view" menu, or if "Auto refresh" is disabled (right-clic on the Waveform etc. window). STEPS TO REPRODUCE 1. Drop a clip on the timeline. The paused image may look normal. 2. Play it 3. OBSERVED RESULT Only part of the image is visible when clip plays, as if the zoom factor was set to 100% (real size, e.g. 1080p clip on a 1080 screen) EXPECTED RESULT Image should be scaled to the size of the monitor window. SOFTWARE/OS VERSIONS Windows: 10 Same problem on both desktop (i3, 8Gb ram, AMD graphics card) and small laptop (celeron, 4Gb, no graphics card), different versions of windows 10. ADDITIONAL INFORMATION KDEnlive standalone version 19.12.2 and 19.12.3 / Doesn't occur in 19.04 Maybe related: nothing is displayed in the waveform/histogram/vectorscope... windows (works fine in 19.04)
I just decompressed and tried "kdenlive-master-328-windows-mingw_64-gcc.7z" and it seems the issues I reported have been solved. Plus, it is possible to type in numbers for example in "change speed", which is another problem I was about to report.
