P: Artboards get messed up when dragging multiple artboards

Thank you for the additional details.

Another observation: the problem seems to happen at any zoom level. However, once glitches present themselves, they seem to 'stick' to zoom levels of ~65% and up. This is a typical example:

• I'm at 100% zoom level, and I move a couple of artboards - positional glitching appears
• I use my mouse scrollwheel to zoom in and out, in and out
• At any zoom level below ~65%, the glitches disappear, and the artboard contents 'snap back' into their correct places.
• But at any zoom level above ~65%, the glitches reappear. 
• Trying to force a screen redraw by dragging the canvas, dragging the contents off-screen then back on, toggling rulers, or changing screen mode, doesn't usually help. 
• Saving the file does usually (always?) help. 

I was wondering if the "Cache Levels" setting had anything to do with it, so experimented with various levels (2, 3, 😎 but it didn't seem to make any difference. 

No, enabling/disabling rulers/grids/smartguides doesn't seem to make a difference. Neither does enabling/disabling "Auto-size canvas" in Artboard options bar

Curious if disabling rulers makes this behave better?

Thanks. Let me see if that helps us reproduce. Will let you know.

FYI
I've just upgraded my nvidia driver (from 436.48 to 445.75), in case that was the issue, but the problem still persists. 

Also, turning off "use GPU" in PS settings doesn't help either. Performance is greatly decreased, but the glitches are still there. 

Here's a simple PSD that I can confirm displays similar problems on my end: https://1drv.ms/u/s!ArgAg1qAY1amkalEhPel0Mwy30bcvQ?e=w8AS9e

If it doesn't have problems immediately, just keep dragging multiple artboards around at different combinations of distances and zoom levels, and the glitches may emerge.

It seems like complexity has something to do with the problem: on my large PSDs with dozens of artboards and hundreds of layers, the glitches are more or less constant, immediate, and severe. Though this new PSD that I just uploaded worked fine for the first little while, but eventually showed the same types of glitches when I persisted.

I've noticed that it may be a display issue only, as if I save the file (or sometimes, change zoom level) then everything seems to pop back into where it's supposed to be. Perhaps a GPU-rendering issue? 

I can give you the original file screenshotted above if you give me a private channel through which to do so. 

Also let me know if you need any of my software/settings/hardware details

@74350, would it be possible to get a copy of your file? Engineering has not been able to reproduce exactly what you're seeing.
