CAUTION: Photoshop CC 2018 Latest Release Broken With Dual Displays (Unusable for Me)

The word from Adobe is that this issue is being worked on—with alacrity I hope.

...

Installing older version of Photoshop
(after uninstalling)

I use dual displays. I don’t think this issue exists with a single display.

I’ve been reporting (to Adobe) dual-screen issues for years now, but they have never been fixed in spite of detailed description of the problem. I accepted that with resignation.

But now whatever bad code was causing that problem has been let loose in the latest release of Photoshop CC. It appears to me that the code involved uses the 2nd screen dimensions and pixel scaling to zoom a window on the primary screen. This latest release breaks in all window modes.

  • Zooming, Fit to Window, Actual Pixels broken
  • Crop tool broken
  • My palette positions are problematic, with the tools palette off the top of the 2nd screen so I cannot move it back into position without changing Display => Arrangement. But that messes up the other palettes, so it is a complete redo.
  • Probably more, but I can’t work with this version so I am going to revert to the prior version.

Here is how to revert to a prior version of an Adobe application. It is relatively painless, but be sure not to delete prior settings when uninstalling.

Adobe: Install previous versions of apps

All window modes are affected: both full screen modes and even normal window mode with a title bar.

Dual displays arrangement: NEC PA302W 2560 X 1600 as primary display plus
(to the left), the iMac 5K 5120 X 2880 @ 2:1 scaling (“looks like” 2560 X 1440)

Below, the Image Size window is shown to demonstrate that going to Actual Pixels on a 2560 X 1600 display is seriously messed up. The window was brought up after Actual Pixels.

After View => 100% for 3064 X 2298 image on 2560 X 1600 display
January release of Photoshop CC 2018 is broken for zooming, Fit to Window, Actual Pixels, Cropping in all window modes

I note your problems with PS and Dual Displays - as an FYI the latest security update of OS X 10.12.6 (2018-001) removed Dual Display capability from my MP 5,1. I am using a flashed Nvidia GeForce GTX980 card and the upgrade caused the Nvidia Drivers to be inoperable. The result was loss of the Dual Display capability and reverting to the OS X drivers to run the display(s) - this did not work well and only one display.

Fortunately, Nvidia yesterday made a new Driver available that solved the problem

I understand that your issue is specifically with PS, but the purpose of this note is to advise you that the exact same problem manifested itself in other areas when the new security patch was released.

Coincidence?

DIGLLOYD: could be one of those wonderful new Apple bugs aka Apple Core Rot, which I’ve been writing about for 5 years. I don’t know yet.
