I’ve been running into a strange issue on KDE Plasma where the entire desktop becomes unresponsive during longer video exports from capcut free. The editor itself starts fine and playback is smooth, but once rendering begins, Plasma starts lagging badly and sometimes freezes completely for 10–20 seconds.
What’s odd is that audio continues in the background and GPU usage spikes heavily right before the freeze. I’m on Wayland with updated Mesa drivers, so I’m not sure whether this is a compositor issue, GPU acceleration problem, or something related to recent Plasma updates.
Has anyone else experienced desktop freezes specifically during GPU-heavy rendering tasks?
