SC <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #5 from SC <[email protected]> --- I came here to report this. It occurs no matter the GPU on both X11 and Wayland. Only kwin surfaces are affected; other applications remain responsive. Attaching strace to the kwin_x11 process seemed to prevent the freeze which indicates a race condition triggered by the timing of XCB events from the KVM disconnect/reconnect. During freeze, per-thread wchan shows 40+ threads blocked on futex_wait_queue compared to ~10 threads in normal state, with thread count growing on each KVM switch. KDE Plasma 6.3.6 / kwin 6.3.6, Debian 13 The bug didn't occur on Debian 11 with the same hardware and KVM switch (kernel 5.10, Plasma 5). -- You are receiving this mail because: You are watching all bug changes.
