Scene view is flickering with artifacts and red/blue color when Graphics API is set to "OpenGLCore" on Linux

Steps to reproduce:

1. Create a new 3D URP project
2. Go to Edit > Project Settings > Player
3. Make sure under "Graphics API for Linux" that "OpenGLCore" is at the top and active
4. Observe the Scene view

Actual results: Scene view is flickering with red/blue colors and black artifacts

Expected results: Scene view renders correctly without any flickering or color artifacts

Reproducible with versions: 6000.0.71f1, 6000.3.13f1, 6000.4.1f1, 6000.5.0b3, 6000.6.0a2

Tested on (OS): Ubuntu 22.04 - reproduces, Ubuntu 24.04, Windows 11, macOS 26.3 -does not reproduce

Notes:

• The issue is likely very machine-specific, and seems to come out of nowhere as it was working fine before. Could be some third-party/driver issue
• Does not reproduce with Vulkan
• Game view renders with no artifacts
• Hardware/System Context:
  CPU: Intel Core i7-8850H
  Graphics: Mesa Intel UHD Graphics 630
  Windowing System: X11
• This was observed while accessing the machine via remote desktop
