SUMMARY When I record a rectangular region of my screen for a few seconds and click on the red dot in the traybar to stop the recording, the recording stops, but it takes another ~30 seconds until Spectacle finally writes the file and shows its window again. Journalctl has logged the following: While recording > kpipewire_record_logging: Filter queue is full, dropping frame 19184 is spammed. When clicking on the red dot, this spam stops and and after roughly 32seconds it printed: > qt.multimedia.ffmpeg.mediadataholder: AVStream duration -9223372036854775808 is invalid. Taking it from the metadata * When I open the webm file in VLC, it shows a duration of 19 seconds, same as KDEnlive. * KDEenlive shows 12 seconds of actual recording and 6 seconds emptiness at the end. * The "Filter queue is full" spam stopped immediately, when I clicked on the red dot: This was 16 seconds after starting the recording.

Maybe this is a way to reproduce it :) fwiw, I have recorded the whole screen except the panel in a rect region, while konsole + journalctl -f was running maximized.

The time to save the file strongly depends on the dimension of the recent angular region recorded: a 100x200 px region is saved quasi immediately, while a full hd width, 300 px region takes a few seconds already.
File is saved immediately with mp4/h264, though there are also some warnings/erros in the log: ``` spectacle[139795]: [libx264 @ 0x7f08bc0228c0] -qscale is ignored, -crf is recommended. spectacle[139795]: [libx264 @ 0x7f08bc0228c0] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 spectacle[139795]: [libx264 @ 0x7f08bc0228c0] profile Main, level 6.1, 4:2:0, 8-bit spectacle[139795]: kpipewire_dmabuf_logging: eglChooseConfig returned this many configs: 1 plasmashell[3239]: QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0 plasmashell[3239]: The cached device pixel ratio value was stale on window update.

Can confirm.

The Qt bug is unrelated and basically harmless as far as I can tell.
