After the latest update I started encountering a rendering / window refresh issue, that manifests during recording and sometimes during fast seek / zoom operations. Everything except the main control bar and timeline becomes invisible, sometimes the updated elements like time display flash into view for a brief moment only to disappear again. There is a workaround - after opening options, going into UI settings and confirming with OK button makes this bug go away. It doesn’t affect any functionality of the application, but it is really annoying, especially when I want to have a constant view of the recording waveform. I attach a video recording of the issue.
Please let me know if I can apply any workarounds or maybe further help in diagnosing the issue.
