I have added a "PTC v57" Tag to the longstanding and still very active "PTC v56 - Flashing white/colored pixel artifact problem (introduced around v53)" thread, so that the conversation of the issue can still continue without having to start all over again.
This is important as the thread is linked to in about a half dozen outside forums (virtual desktop, reddit etc) who use it to keep updated about the progress on this issue and potential fixes - the thread is still used daily with about 8000 current views.
I have checked and this thread does now appear in the search link provided by Ryanality above. I hope the thread issue can continue in this manner.
