Created attachment 278839 [details] video showing the animating glitch/leak OVERVIEW: Switching to a TTY console (eg: CTRL + ALT + F1) from X desktop is causing an overlayed glitch to reveal itself ~90% of the time. It seems like a memory/data leak, not just a graphical leak. 1. Sometimes the glitch animates, reflecting system activity. (eg: in the attached video, nmap was running in the background, and the glitch animates in a particular section. Sometimes, other parts animate reflecting other activity) 2. The glitch remains in the same place overlaying the console, regardless of scrolling activity. i have tried different Kernel versions, and differing versions of ubuntu & debian distributions. Most recently i have compiled 4.18.9 after i changed more .config settings before Kernel compilation, to see if i could root it out, but the glitch still occurs. STEPS TO REPRODUCE: 1. invoke X graphical desktop 2. switch back to a TTY, eg: using CTRL + ALT + F1 CURRENT BUILD & HARDWARE: Kernel: Linux 4.18.9 SMP PREEMPT Distro: Debian GNU/Linux 9.5 (Stretch) CPU: Intel Core i7-7700K CPU microcode: 0x8e Display GPU: Intel (i915) i have PCIe GPUs inside KVM guests with no amd or nvidia drivers on the host. ######################## ### FUTHER lshw INFO ###
