Created attachment 405564 [details] Testcase Overview: Audio produced by the WebAudio framework Tone.js lags, stutters, and sometimes does not play at all when using Webkit2GTK or on the GNOME Web browser. Steps to reproduce: – Run main.py in the testcase – Press the play button Actual results: Notes play unpredictably, with different timing each time. Expected results: Each note should be played 0.5 sec after another consistently. Build 2020-07-30 on VirtualBox Fedora 32 (bug also occurs outside of a VM) Doesn't occur on other web browsers like Chrome.
