The mouse cursor freezes for about half a second, and occasionally the system audio also cuts out briefly. This happens irregularly but repeatedly. The issue started after updating to Linux 7.0.0‑14‑generic. Around the same time, linux‑firmware was also updated, so I cannot determine which change might be responsible. On my laptop (Intel + Nvidia) I cannot reproduce the issue, but another user with AMD hardware reported similar symptoms on Discourse. Affected hardware: · CPU: AMD Ryzen 5 9600X (12) @ 5.49 GHz · GPU: AMD Radeon RX 9060 XT · OS: Ubuntu 26.04 Observed behaviour: · Mouse cursor freezes for ~0.5 seconds (“micro‑stutter”). · Occasional short audio dropouts. · I have not noticed the issue while gaming, although another user claims it also happens there. I would appreciate guidance on additional tools or diagnostics that could help identify the root cause. At the moment, the only evidence I can provide is the observed behaviour described above.
