Public bug reported:
Since updating to kernel 7.0.0-38-generic, the display shows brief
flashes of noise (roughly 0.1 seconds or shorter). The issue is not
present with kernel 7.0.0-34-generic.
Regression confirmed by booting between the two kernels on identical
hardware and configuration: 7.0.0-34 is clean, 7.0.0-38 exhibits the
noise flashes.
Hardware: Slimbook EVO 14
GPU: AMD Strix [Radeon 880M
OS: Slimbook OS 26 (based on Ubuntu 26.04 LTS), stock Ubuntu kernel
via linux-image-generic-hwe-26.04 track (7.0.0-38.38 from the
standard Ubuntu archive)
Happy to attach full dmesg/journalctl output from a 7.0.0-38
session; currently booted into 7.0.0-34 as a workaround.
