Environment:

OS: Windows 11 64-bit
CPU: Intel Core i7-14700K
GPU: NVIDIA RTX 2000 Ada Generation
Photoshop Version: 27.10
Driver: NVIDIA Studio Driver

Issue Description: Immediately after updating to Photoshop v27.10, severe UI and canvas rendering issues began occurring during normal editing. The symptoms include:

Rapid flickering where UI elements and the canvas temporarily disappear and instantly reappear (no black or white flashes).
When navigating menus (e.g., Preferences), the text briefly vanishes and comes back.
While editing, the active photo disappears from the canvas and instantly reappears.
The flickering happens extremely fast, rendering the application completely unusable for daily work.
This issue is isolated to Photoshop and does not occur in other applications.

Troubleshooting Steps Executed:

Verified the monitor is connected directly to the NVIDIA GPU, bypassing the Intel iGPU.
Forced High Performance GPU assignment for photoshop.exe via Windows 11 Graphics Settings.
Disabled Hardware-Accelerated GPU Scheduling (HAGS) in Windows.
Disabled Multi-Plane Overlay (MPO) via the Windows Registry.
Disabled GPU Compositing and OpenCL in Photoshop's Advanced Graphics Settings.

Results: The rapid flickering persists despite all GPU and OS-level troubleshooting. The issue is only resolved when Use Graphics Processor is completely disabled in Photoshop Preferences, or when rolling back the installation to v27.9.1. This strongly indicates a regression in GPU rendering specific to v27.10.

Hey All! Thank you all for reporting this and for the detailed system info; it's been very helpful.

We've been able to reproduce the UI/canvas flickering issue in Photoshop 27.10, where the screen intermittently darkens and flashes internally. It has been filed with the engineering team for investigation.

For now, these are the workarounds:

Downgrade to Photoshop 27.9.1 via the Creative Cloud app (Other versions > 27.9.1).
Go to Edit > Preferences > Performance > uncheck "Foreground Composite Cache" and "Use GPU Compositing." from Advanced settings. (Suggested, not verified)

Colors shifting on canvas is another issue that has surfaced with PS v27.10, it is being tracked here:

We understand this disrupts the core editing workflow and appreciate your patience. We'll update this thread as we have more information.
