Bug ID: 495682
Summary: abysmal performance/freezes without audio output

Product: kdenlive
Version: 24.08.2
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: major
Priority: NOR
Component: User Interface & Miscellaneous
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---

* just turning the headset on is enough to fix this
* OR changing the backend from SDL to RtAudio
because I first suspected HW acceleration, general performance issues, ..
