Created attachment 144771 [details] Kernel log Arch Linux Lenovo E485 (16 GiB RAM) AMD Ryzen 2500U xorg-server 1.20.5-2 mesa 19.1.2-1 xf86-video-amdgpu 19.0.1-1 libdrm 2.4.99-1 After upgrading to the linux kernel 5.2 from the Arch Linux repositories, my laptop started to show graphical corruption in Firefox or Konsole. It is much worse if something is moving on the screen e.g., a video is playing. Sometimes Firefox is almost unusable as a result. A downgrade to 5.1.16 immediately fixes the issues. Somebody mentioned similar corruption for bug 109206: https://bugs.freedesktop.org/show_bug.cgi?id=109206#c57 My kernel command line is: initrd=\amd-ucode.img initrd=\initramfs-linux.img root=PARTUUID=34098e4c-f1bf-4a43-a0a8-2ba3ed3c71a6 idle=nomwait psmouse.synaptics_intertouch=1 acpi_osi=Linux amdgpu.gpu_recovery=1 ivrs_ioapic[32]=00:14.0 I used to have iommu=pt or iommu=off on the command line to get this laptop to boot properly but I have not needed that switch for a while. I might try to reintroduce it with 5.2 just to see what happens. In any case, my setup worked before, so something does not seem right.
