Inpainting tool not working

[Maize]

So i have been scouring the help forums here looking for an answer and i cannot find one that works.. 
I have been send an image from a family member to clean up the floor of a phot around her new puppy so she can frame it. 

how ever when i use the inpainting tool, no matter what option i use, i cannot get it to work correctly. It simply shows the red, shows some calculation is happening, but doesn't perform the actual inpaint. 

I have disabled hard acceleratoion and reenabled it, 
i have restarted photo2 
i have created new files and tried,
I have tried using different photos.
I have attempted a reinstall as well.

Cheers in advance.

Here is a video of said issue

Ahhhh never mind, i found the issue, I had a Noob moment:
- It was the brush settings set to low
How ever I would of thought that the data from my user settings like brushes would not have come back after a reinstall.
now that I think about it, my UI settings didn't need to be reconfigured either.... 

In any case i noticed that the opacity was set to 10% instead of 100%, (Not sure how that occurred on that tool)

I put this update here mainly in case someone else has this issue. they have another thing that could cause that and is "perceived" as an issue when its just PEBCAK error (problem exists between chair and keyboard.)

This almost certainly is the result of you accidentally pressing the ! key on the keyboard. There is a hardwired (unchangeable) set of opacity shortcuts built into the UI: tapping once on any of the number keys sets the opacity to 10X that% opacity; & tapping two numbers quickly, one after the other sets it to that % (so tapping 2 then 6 for example sets it to 26%).

You can reset it to 100% by tapping zero quickly twice in a row.

Hard to describe but if you try various combinations in a row you should see how it works.

@R C-R Thanks i will definitely try that out, that would a lot of sense actually as to how that came about. Thats really good to know.
