Created attachment 141333 [details] backtrace of OverviewWidget stroke spawning thread For unknown reasons, OverviewWidget::generateThumbnail will repeatedly start a stroke to generate the thumbnail, which triggers thread spawns about every one second due to existing inefficiency with the thread pool implementation. It seems to happen after creating/opening a file, closing it and then creating another file. (Note that this report is not about fixing the thread pool implementation.) I have observed this behaviour with commit e7580089 on Linux docker build and 6ca8117 on Windows nightly build.
