wxMaxima until about 2 months ago for showing thechelp system used wxHtmlHelpCtrl from wxWidgets. And that control used wxWebView. So you might be right about what control triggered the warning. The current wxMaxima master has a performance issue. Once that is resolved I will try to upload a new release to Debian-testing.
As best as I can tell, wxHtmlHelpCtrl does *not* use wxWebView. So I think that is probably not where this is coming from.
