-Subject: fix: add support for skipping first no-op refresh in thumb cap
+Subject: fix: add support for skipping first 2 no-op refreshes in thumb cap
 
 Fixes a bug in the SCK thumbnail capturer, will be reported upstream for a hopefully
 less hacky fix.
 
+The first refresh is "no windows yet, no thumbnails".
+The second refresh is "we have windows, we queued the thumbnail requests"
+The third refresh (the one we want) is "we have windows, and have thumbnail requests"
+
+This really isn't ideal at all, we need to refactor desktopCapturer (read completely re-implement it)
+to use StartUpdating and handle the events instead of using the "get the list once" method.
