What are your PC specifications?
CPU: Ryzen 7 PRO 6850H with 680M iGPU
eGPU: Radeon 7600M XT (via OCuLink, default)
AMD Driver: 26.2.2 (via Adrenalin)
RAM: ADATA 32GB DDR5-4800 (16GB x 2)
SSD: Crucial P3 Plus 4TB (PCIe 4.0 x4)
OS: Win11 Pro 25H2 b26200.7922
Note:
Switching between 680M (iGPU) and 7600M XT (eGPU) has the same behaviour.
Is there anything else that can help developers narrow down the issue?
The issue appears to have been reported on multiple occasions. All of them involve AMD:

Thought a formal ticket can help launch a proper investigation.
