P: Zoom tool doesn't do the right thing if canvas is rotated

As Adam Taloy described above, I have exact same issue after updated to 2020
I'm attaching a video I recorded. This is so annoying,,,

Hello, indeed, it is not listed on the fixed issues page: https://helpx.adobe.com/photoshop/kb/fixed-issues.html make sure to check it regularly!

Today I updated Photoshop to version 21.0.1, but the problem with scaling remained 😞

I'm also having this issue on 21.0.0.  Zoom seems all messed up- hard to describe but I think it's zooming as if the canvas isn't rotated even when it is.
Happens with the zoom tool whilst clicking, or using the hotkeys (Z or ctrl + space).

As a frequent user of the rotate and zoom hotkeys, I look forward to this being fixed.

In Photoshop (v21.0), if zooming is performed with View> Flip Horizontal (Ctrl + Shift + D) turned on, it will always move to the left.
When I want to zoom to the right side, move the cursor to the right side and perform zooming, but even in that case, it will be zoomed in so that it can be drawn to the left side, which is very inconvenient.

It was normal with the horizontal flip turned off, and this problem was not seen in the previous version (v20).

Photoshop (v21.0)にて、表示>水平方向に反転(Ctrl+Shift+D)をONの状態でズームを行うと必ず左側へ寄ってしまいます。
右側にズームさせたい場合は右側にカーソルを持っていき、ズームを行いますが、その場合でも左側に吸い寄せられるようにズームされてしまい、とても不便です。

水平方向へ反転をOFFの状態では正常であり、前バージョン(v20)でもこのような問題は見られませんでした。

I have the same problem since the update, also only when canvas is rotated. (using Mac OS high sierra 10.13.6)

Hi, just jumping in to report that I'm experiencing the same weird zoom behavior as well. Copy-pasting my description from a thread at https://community.adobe.com/t5/Photoshop/PS-2020-Zoom-Shortcuts-Behave-Differently-from-2019/m-p/107...

I just installed PS 2020 and the zooom functions no longer work as they did in 2019. In 2019 the "Zoom In" and "Zoom Out" options under the "View" dropdown menu would use Animated Zoom and zoom towards the screen center. In 2020 these zoom shortcuts no longer use Animated Zoom, and zooming while the view/canvas is rotated has unpredictable results. Zoom sometimes zooms towards screen center, and other times zooms towards points that aren't on screen. These problems with zoom are bad enough that I've got to use 2019 for now.

 For the life of me, I can't figure out how to re-enable this functionality. My settings are exactly as they were in 2019.

Yeah, Windows 10 x64 - Version 1809, with Cumulative Update Package KB4507469. GPU/Performance settings are in an attached image below.

For what it's worth, setting "Drawing Mode" to Basic and Advanced has no effect on this issue. The weird behavior with zooming on rotated views is also present with the Zoom Tool, with or without scrubbing style zoom enabled. In 2019 with these same settings, zooming is working as expected.

Hi Alexis, Thanks for reporting. We've reproduced and are looking into the issue. If this issue is affecting your work, you can install the prior version until the fix is released. https://helpx.adobe.com/download-install/using/install-previous-version.html

Howdy Alexis,

Can you share what you're seeing in more detail?  How is Zoom behaving differently?  What is happening?  Which OS are you on?

Thanks,
David
