[Bug 2169181] Re: Visual background flickering and pixel artifacts after updating to kernel 7.0.0-38 (regression from 7.0.0-34) | Ubuntu 26.04 | AMD Radeon RX 9060

I can also verify that the "dm_handle_vmin_vmax_update [amdgpu] hogged CPU for >10000us" messages do not occur with the previous kernel version I had installed (7.0.0-31-generic), and the bug does not occur. -- You received this bug notification because you are subscribed to linux in Ubuntu.
