P: Photoshop v27.10 UI, Canvas and screen Flickering

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.
