Created attachment 137445 [details] slider jumps to cursor without mouse click SUMMARY When hovering the mouse over a slider the value changes according to the mouse position (as if the mouse button was pressed all the time). That makes it impossible to navigate the UI without changing values. Tested with different kdenlive versions (arch stable 20.12.3, arch unstable 21.03.80, appimage stable 20.12.3). When I revert the package local/qt5-base 5.15.2+kde+r171-2 (qt qt5) to the version local/qt5-base 5.15.2-5 (qt qt5) everything works as expected. But sliders in other qt applications are fine. I assume the effects slider is no standard qt widget(?) so I open the bug here. Tried on different machines: laptop with Cinnamon, desktop with xfce, fresh installed virtual machine with xfce (all Arch). STEPS TO REPRODUCE 1. Arch: Install local/qt5-base 5.15.2+kde+r171-2 (qt qt5) 2. Move the mouse over any slider 3. OBSERVED RESULT Value of that slider instantly "jumps" to the mouse position. EXPECTED RESULT Value of the slider does not change when simply moving the mouse over it. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Just found https://bugreports.qt.io/browse/QTBUG-92504 Seems to be a similar problem?
I don't have this behavior on Windows (tested with nightly #725). Hover over the effect slider doesn't change the value.
I can reproduce as well. Using latest Arch and compiling Kdenlive from Master. Fwiw, this isn't happening in Krita
