Image Handle Will Not Align On A Corner Of Pixel Grid

[Bwp3]

Set view to pixel grid.

On a document background, place an image.

That image will become a smart object.

For that image layer select: Edit> transform> distort

Zoom in to the pixel grid on a handle of the image.

Try to align the handle to a corner on the pixel grid.

The handle will not land on a corner of the pixel grid but jerks away.

Why?

Not a memory problem, sorry.

The above worked for years and then…there was an update and it stopped working.

I have 300 documents that contain 3 images aligned to a grid (The above should say grid not pixel grid, although it is at pixel level magnification.)

I just noticed that when I select distort on a layer in one of the 300, the handle jumps out of alignment and I can’t move it back to the grid corner. When I hit ESC or place, it returns to alignment.

This does seem like a memory problem but the process is heavily CPU and RAM memory changes very little in fact it stays below 50% which means PS is only using one of the 8GB chips.

Graphics card issue?
