There is no rigid pattern, but it consistently triggers when multitasking with resource-heavy or graphical applications under Linux kernel 7.0.0-30-generic. It frequently occurs when opening: - Zoom + VS Code + Terminal simultaneously. - Zoom + VS Code, followed by launching Counter-Strike 2 (CS2). Hardware Environment (Current Desktop): 32 GB RAM AMD RYZEN 5 7640hs 1 TB SSD AMD RADEON graphics Additional Hardware Verification: Note for developers: I have verified that this exact same issue also occurs under identical conditions on my Acer Swift 3 laptop, which runs the following hardware: - CPU: AMD Ryzen 7 5000 Series - GPU: AMD Radeon Graphics - RAM: 16 GB Steps to Reproduce: 1. Boot into the desktop session using kernel 7.0.0-30. 2. Launch combinations of Zoom, VS Code, and a terminal window, or launch Zoom, VS Code, and CS2. 3. The display frozen briefly or immediately crashes, dropping the user session straight back to the login screen. Expected Behavior: The desktop environment should manage the window composition, application load, and graphical rendering without terminating the user session. Actual Behavior: The graphical display server crashes instantly back to the login screen, losing all unsaved work.
