Single Row/Column Marquee issue
I opened an image file.
I selected the single row marquee tool.
I clicked the Move tool icon
I then dragged the top/middle handle upwards on the marquee.
It created a random spread of colours but did not replicate the line of pixels selected - see image.
This is the same with column mode.
I have turned "Use Graphics Processor" on and off but that made no difference.
Photoshop CC 20.0.4
Windows 10.0.17763.404
BTW you can also see the issue at the end of this video Single Row Marquee Tool - Adobe Photoshop CC 2019 - YouTube
