Lasso Tool Lines not showing as I'm selecting

Hi im using Photoshop cc20 whenever i use lasoo tool Photoshop gone to crashed. Can any body help me?

I have had this problem for many years on new photoshops I have to keep reverting to Photoshop elements but I gave the new photoshop a go as I needed the new features as my projects demanded it.

I use the selection tool (the pen tool isn't a good substitute for the method I use) the most out of any tool and have the problem where I am selecting something and suddenly the next line will disappear and is very annoying. 

After trying several methods to fix it from this thread and others across the web nothing worked. 

I recently bought a Pen Graphics tablet and have found if I hold down the stylus on the screen when the error occurs it refreshes the tool and it works at least until the next time it happens then I repeat and continue with my lines. 

I hope this problem is solved soon so I don't have to use this work around but for now I can continue working with this method. 

Not the desired fix but the only work around that seems to work.

After trying ALL of these suggestions with no luck, (Lasso tool would work, but not magnetic or polygonal), I realised it was a problem with my Wacom tablet. Still not sure how to fix it, but at least it works on the normal trackpad.

I am trying to implement your fix using Edit>Preferences>Performance, but the resulting dialog box does not look like the one you posted, nor does it have the USE GRAPHICS PROCESSOR or ADVANCED GRAPHICS PROCESSOR SETTINGS control.

I took a screen shot of my dialog box, but I can't load that into this reply, either!

I unchecked "Use Graphics Processor" before reading on. When I saw that it could cause Photoshop to behave erratically I went back and rechecked it thinking that I would need to find another solution. Just the act of unchecking and rechecking the button seems to have. fixed the problem. I rebooted Photoshop in between.

Update: The problem returned. I switched drawing mode to "Basic" and that worked.

I had the same issue:

Photoshop CC (v20.0.4)

iMac 5K 27" 2017 with Radeon Pro 580 8Gb on High Sierra (10.13.6)

I found if I visited the Performance tab of the preferences, and from the Advanced Settings section of the Graphics Processor Settings Unchecked "Anti-Alias Guides and Paths" I got my marquee back.

I may have found a simpler solution.

If the first file type you open after loading Photoshop is CMYK, the marching ants and transform boundaries don't display.

But if you open up an RGB file, then any CMYK files you open after that will display ants & transform properly.

I was having the same problem with the lasso tool and no marching ants, and i went through the steps you guys have outlined. then i went backward until i got to the point that with advanced on, i could untick "anti-alias guides and paths" and it showed the selection. it may or may not work for you, but if you're looking to preserve some of the GPU power in the PS you might give it a shot.

Basically their solutions to every bug they have in the whole CC suite are to not use any of the new features.

Yes! I am having this problem too! So frustrating. The lines only appear after I have closed the selection.
