Created attachment 155245 [details] Notice the two preview windows - the audio preview looks corrupt, and neither has the scrubber/timeline visible. SUMMARY The bar letting you scrub through the preview of clips and other media is invisible. When viewing audio, the visualization of the waveform is also invisible. I can sometimes get either of these to show up by resizing the preview, but it often appears very buggy. STEPS TO REPRODUCE 1. Open Kdenlive 2. Enter the editing view (To see the broken audio preview:) 3. Open an audio clip 4. Click and drag to resize the top and bottom halves of the window. OBSERVED RESULT The scrubber is invisible. By resizing the top and bottom halves, to might get a buggy view of the audio preview or the scrubber. EXPECTED RESULT The scrubber is always visible SOFTWARE/OS VERSIONS Linux Mint 21.1 Cinnamon 5.6.6 Kdenlive: 22.12.1 Package Type: flatpak MLT: 7.13.0 Qt: 5.15.8 (built against 5.15.7 x86_64-little_endian-lp64) Frameworks: 5.101.0 System: KDE Flatpak runtime Kernel: linux 5.15.0-57-generic CPU: x86_64 Windowing System: xcb Movit (GPU): disabled Track Compositing: qtblend ADDITIONAL INFORMATION I don't remember this happening before a recent update (since the start of this year). However, I tried downgrading to earlier versions and it still occurred, which makes me think it's an issue with something else, maybe qt or the kde framework, or something else in Mint's repository.
Same issue here after upgrading on Elementary OS 6.1, kernel 5.15.0-56-generic, Flatpak 1.12.7
Same issue here, Fedora 37 KDE + flatpak. I tried to reset my preferences, but nothing changed. I then found the report here. The scrubber is invisible, but dragging in the empty gray area where it is supposed to be still browses the video. So it's a display issue. Same for audio scrubbing. With three feedback, I turn this issue to "confirmed".
I should add that this bug does *not* occur with the appimage (22.12.1). I haven't tried the packaged version.
I can confirm @JulianHeuser, same here: appimage has them visible. I also can't get the usual overlay toolbar on the rendering preview, (it pops while the mouse hovers the video). Unfortunately for me, the appimage crashes when I open my project, has missing fonts and the only one that doesn't do that is the 21.04.0x (but is not retro compatible to open my kdenlive project started with 22.12.1 so I'm stuck with the bug and limited features.)
Created attachment 155497 [details] Location of the issue: missing features.
Additional info: I tried to roll back the Faltpak to a version of November (22.08.3); the problem is also in it. to list previous version available: $ flatpak remote-info --log flathub org.kde.kdenlive to downgrade to a previous version (the oldest I could find): $ flatpak update --commit=5b9cedab06942d4c0580f7bc36cf6eb3cd2a1294ebb1ddda8421eb1c944c7e4a org.kde.kdenlive to revert back to most recent, just: $ flatpak update
Looks like this is really an issue with the flatpak KDE runtime that kdenlive uses (org.kde.Platform/x86_64/5.15-21.08). I downgraded to commit 128ca4eb23159403e8443b4faa87c6dcbc1bf716d73f671d0839d318c2b34232 and the scrubbers are back, and audio previews work perfectly. Fortunately we can narrow it down pretty easily, the next commit (2e4ed12dc21144c4bd7bcef988d74b8f079a50258dce3a433a880e6b2196fc76) breaks it. That narrows it down to some commit between Dec 22 and Jan 9.
