Created attachment 178318 [details] Coredump for spectacle SUMMARY When I try to record even the shortest video as a webm file (which is the default) Spectacle hangs for a while, seems to only try to encode after the fact only on a single core. If I make a 2 second video I can get back a result after ~30 seconds... STEPS TO REPRODUCE 1. Open spectacle 2. Record full screen 3. Stop the recording OBSERVED RESULT Spectacle is not responding anymore and it seems like it will never save the file (even though it does after a disproportionally long time). I also get some weird logs (only the ones after stopping the recording): ``` [libvpx-vp9 @ 0x7f83c0652340] v1.15.0 qt.multimedia.ffmpeg.mediadataholder: AVStream duration -9223372036854775808 is invalid. Taking it from the metadata vaExportSurfaceHandle failed failed to get textures for frame; format: 44 ``` EXPECTED RESULT The recording should finish quicker and preferrably asynchronously because blocking the window loop doesn't seem like a good UX. SOFTWARE/OS VERSIONS Operating System: NixOS 25.05 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.2 Kernel Version: 6.12.12 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 2600 Six-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 ADDITIONAL INFORMATION I only received one coredump but this seems unrelated to the issue. Attached anyways.
Hi - I can't personally reproduce (a 10 second recording saves in about 3-4 seconds), but I wonder if this is somehow related to https://bugs.kde.org/show_bug.cgi?id=488896 , which is in turn possibly related to https://bugs.kde.org/show_bug.cgi?id=492844 When the video does save, is the result a smooth recording, or one with lots of dropped frames? Thanks!

Whoops, sorry for not responding for a while. I was using the version from KDE Gear 24.12.2: https://kde.org/info/releases-24.12.2/ But now my distro (nixpkgs) ships the version that's included in KDE Plasma 6.3.3. Now it seems to be fixed. A 10 second video saves within a couple seconds and the video quality can be blocky but definitely cromulent to show what is going on.
