Brush tool creates white boxes when used

[nithulanj93380182]

The brush tool will randomly create white boxes when used. The boxes will move around and vary in size. The white boxes only seem to appear when the brush is used on certain areas of the canvas, but these areas are completely random. The brush still works, if you save the work even if the white boxes are around, close the image and then open it again then everything that the brush touched has been changed, even if the boxes hid it. Sometimes if you start using the brush without zooming into the image nothing is wrong, but the moment you zoom into the image the white box bug begins.

Hi @nithulanj93380182 

Go to Preferences > Technology Previews... and enable “Older GPU mode (pre 2016)” - Restart Photoshop. Does the problem persist?

That fixed it. Thanks
