Just updated to 26.10. Zooming is still wonky. Zooming with CTRL + and - still works better when the contextual task bar is hidden. Really hoped Adobe would have fixed it by now.

 I've encountered a bug in both the official and Beta versions of Photoshop 2025. After changing the layer thumbnail size in the Layers panel from “Small Thumbnails” to “Medium” or “Large,” the zoom shortcut (Ctrl + + / Ctrl + -) starts behaving abnormally. As long as the Ctrl key is held down, the zoom keeps repeating automatically, causing the canvas to zoom in or out continuously. Even reverting the thumbnail size back to “Small” doesn't fix the issue. The only workaround I've found is to reset Photoshop preferences, which temporarily resolves the problem. This suggests the bug may be triggered by a specific preference setting related to thumbnail size.

Environment:

• Photoshop version: 2025 (official release and Beta)

• OS: Windows 11

• Input method: Keyboard shortcut (Ctrl + + / Ctrl + -)

Photoshop 2025 缩略图设置导致缩放快捷键异常

我在 Photoshop 2025 的正式版和 Beta 版中发现一个 Bug：当我将图层面板中的缩略图大小从“小缩略图”改为“中”或“大”之后，使用 Ctrl + + 或 Ctrl + - 进行缩放时，只要不松开 Ctrl 键，缩放操作就会持续进行，导致画面不断放大或缩小。 即使我将缩略图大小改回“小缩略图”，问题仍然存在。 只有在重置 Photoshop 的首选项后，这个问题才会消失。 这可能是某个首选项设置引发的 Bug，希望 Adobe 团队能关注并修复这个问题。

环境信息：

• Photoshop 版本：2025 正式版和 Beta 版

• 操作系统：Windows 11

• 输入方式：键盘快捷键（Ctrl + + / Ctrl + -）

Additional Information: After resetting Photoshop preferences this time, when using Ctrl + + or Ctrl + - to zoom, holding down the Ctrl key causes the zoom action to repeat twice (instead of once). If I then change the layer thumbnail size in the Layers panel (e.g., from “Small Thumbnails” to “Medium” or “Large”), this behavior changes to infinite continuous zoom until the Ctrl key is released. I am currently attempting to completely resolve the issue by uninstalling Photoshop and deleting the preferences file.

补充情况： 在我这一次重置 Photoshop 首选项后，使用 Ctrl + + 或 Ctrl + - 进行缩放时，长按 Ctrl 键会连续触发 两次 缩放（而不是一次）。 当我再次修改图层面板的缩略图尺寸（例如从“小缩略图”改为“中”或“大”）后，这个行为会变成无限连续缩放，直到松开 Ctrl 键为止。 目前我正尝试通过卸载 Photoshop 并删除首选项文件的方式来彻底解决这个问题。

Hello, did you try to turn off your gpu performance of photoshop 

Test with GPU Acceleration Disabled

Several layers-panel oddities or UI glitches in Photoshop have been linked to GPU issues. Disabling GPU-related options may help isolate the problem:

Go to Preferences → Performance

Uncheck options like Use Graphics Processor, as well as anything mentioning OpenCL, Use Legacy Compositing, or Use Hardware Accelerated Rendering

Restart Photoshop and test the behavior again

Thank you for your suggestion. I disabled the GPU-related settings as advised, but unfortunately the issue remains unchanged.

@iSec_1234 it's a known issue, as a workaround hide the contextual task bar

oh okay thx

[Chris Maddrell]

Ctrl + +/- zoom etc has gone bonkers!!! One click used to do about 25%, now it does c.250%!! Windows 11 with wired mouse & keyboard. 
Is there a new way of zooming?!

@Chris Maddrell it's a known issue in versions 26.9 and 26.10, as a workaround hide the contextual task bar

[Chris Maddrell]

Thanks for the tip. I did search for this problem in the community before posting my question and no info came up!

This major bug is STILL here in version 26.9, and the beta of 26.10. 

Tested on two separate machines.

Breaking basic shortcuts for zooming in/out is a rather bad bug - this needs to be higher priority.
