I can reproduce on Fedora KDE 42 - just to note, the cause could possibly still be linked to the OSD, but the issue seems to occur even if the OSD is disabled. Thanks! *** Bug 503476 has been marked as a duplicate of this bug. *** Trying this out on all my available devices, since I noticed the three folks who directly observed it all have NVIDIA cards - which sent the alarm bells ringing... * NVIDIA graphics: slider just stops moving until it suddenly appears in the new position * Unaccelerated graphics (VM): slider moves at a low framerate, and lags behind the cursor * AMD graphics: seems *almost* perfectly smooth So perhaps there's some graphics driver issue? It's reproducible using nouveau and proprietary drivers. Sorry for double message, I need to add that I can't test on AMD GPU because I don't have one unfortunately. *** Bug 504802 has been marked as a duplicate of this bug. *** I can confirm that it is smooth on AMD (and X11), however on my secondary laptop with an Intel processor (i5-8250U) and Wayland it lags terribly. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Endeavour OS KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.1 Sorry for the unintended spam - I switched to X11 to debug another issue and this one appears to be different. Sometimes it lags, sometimes it doesn't; when it doesn't, however, it starts adjusting the volume after a couple of seconds, enough so that I have already closed the widget and it therefore makes random adjustments. Supremely weird! |
Created attachment 180690 [details] showcase SUMMARY Volume bar in the Audio Volume widget freezes until OSD audio volume completes its animation. Also, I think it's redundant to have OSD in this case because the volume percentage is already displayed in the audio volume widget and user is focused on it so maybe not display it at all? STEPS TO REPRODUCE 1. Change the audio volume in fast motion using the audio volume widget OBSERVED RESULT Widget volume is frozen when user moves the volume fast EXPECTED RESULT Widget volume is not frozen SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 Kernel Version: 6.14.3-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-6600K CPU @ 3.50GHz Memory: 7.7 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 970
