WebFeb 18, 2024 · Hi, I have noticed a choppy GUI rendering after a recent system update to linux 5.16.1.arch1-1. Whenever the computer has to load or newly display something - for example images while scrolling the webpage, the whole display together with the mouse cursor freezes for ~0.2s to 1s. Once the freeze lasted for ~10s. WebOn MDS affected CPUs, the kernel already invokes CPU buffer clear on kernel/userspace, hypervisor/guest and C-state (idle) transitions. No additional mitigation is needed on such CPUs. For CPUs not affected by MDS or TAA, mitigation is needed only for the attacker with MMIO capability. Therefore, VERW is not required for kernel/userspace.
