Problem with Screen Cursor (and keyboard) Surface Pro 4, Windows 10 Pro

Question

My cursor starts to flash and is difficult to use when it is flashing. It appears it has something to do with a transparent Semi Circle that appears in the upper part and slightly above the right end of the taskbar. If, using my finger, I touch the screen within the semi circle, I can drag a solid cursor onto the screen to use. However, it usually starts flashing again and I have to do it again. Sometimes, a short white vertical line appears about 3/4 up the screen from the bottom, also on the right edge of the screen, and I have to pull the cursor from that location instead of the semi circle on the bottom. 

This started immediately after I had a cracked screen repaired. I took it back to the repair person, and was told "It was nothing I've done", I can't help you and I cannot give you your money ($220) back. I suspect it was her fault, but I do not know what to do in this situation. Also my keyboard stopped working a couple of days after the repair. I'm am now using a Bluetooth keyboard to type this out.

Even Microsoft does not replace/repair cracked screens because of possible

damage - and many find that their devices are totally unusable/bricked when they

attempt to do this with a third party vendor. Unfortunately, this is really

between you and the repair person.

Oh, I was aware of that, and I'm sure i'm out of the repair money. But my question is ... What can I do to work around this irritant? I wish to continue using the Surface and there must be something I can do. 

I have already tried resetting the surface. That did not work, so I tried something that Microsoft warned against, but I thought it might help ... that is I stopped encryption on the Hard Drive,  went into the BIOS, turned off "Safe Boot", placed a USB Boot drive with Windows 10 Pro on it, along with a Keyboard and a mouse attached to USB Hub into the USB slot, and booted to first wipe the drive completely and then to install Windows 10 Pro. I then went to Surface Support and installed the necessary drivers for the Surface. All went OK, but that darn cursor problem continues.

I'm sorry, there is nothing we can suggest to work around the damaged caused

when the vendor replaced your screen. We don't know what damage was caused by

this repair, but it is hardware related and not software. If the vendor does not

guarantee their work, perhaps the credit card company you used to pay for this

will assist in getting a refund for the work they performed.
