Windows 10: Strange, recurring mark on screen

My screen has recently begun to feature a strange mark once again. This mark appears to be physical damage on the screen until I move my cursor to it, at which point I can mostly cover it with the cursor. Other than that it always stays in the same place and covers apparently all other content on my screen besides the cursor. This is the second time I've encountered it since April 1.


It looks like this:


And here it is on Wikipedia, for example:



What is this?? Is there a reason it's showing up? What makes it, and how can I reliably remove it? Big apologies if this forum simply is not the correct place.

AMD FX OC'ers Club

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

 

Microsoft To-Do - Duplicate Recurring Tasks

All my recurring tasks in the To-Do app are being duplicated. So when I mark a recurring task complete, an exact copy of that occurrence appears on the list with the same due date and sub tasks, but the task and all sub tasks are marked incomplete. This
means that I have to check every sub task and main task complete twice for every recurring task I have. Before marking the next occurrence complete, only one instance of that recurring task appears on the list.

I tried deleting all my recurring tasks (including all previously completed occurrences) and creating the recurring tasks again from scratch, but I am still encountering the same problem.

How do I get rid of the duplicate occurrences permanently and prevent them from being created again?

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
