I am on an Asus UX305UA-FC057T - Intel Core i7-6500U - Intel HD Graphics 5500 when using kernel above > 4.2, I observe punctual screen glitch similar to those seen on image linked. This happens through the usage of cinamon (3d) on linux mint. But still I do use version 4.5.2 compiled by myself. uname -a Linux yves-asus 4.5.2 #2 SMP Sun Apr 24 20:17:09 CEST 2016 x86_64 x86_64 x86_64 GNU/Linux The glitch happens only with new kernel, previous kernel like 4.2.xxx are working fine for display with same system (they have othere issues). And seems (as a user point of view) be linked to a certain pattern: menu compositing + mouse hovering. Image showing the issue https://forums.linuxmint.com/download/file.php?id=26842&sid=ae05af439953d8fac51a9658d2eba0c1&mode=view it's flickering: so the screen is scrambled, and then normal Thank you for your time, Yves
there is another issue: resuming from suspend to ram is failing, I would have filled a separate bug, but apparently it can be linked to graphics. following the instruction here: https://01.org/linuxgraphics/documentation/development/how-debug-suspend-resume-issues S3 suspend (a.k.a Suspend To RAM): dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after the machine go to sleep : led blinking after pressing power button, make machine reboot. but dmesg_after exists with same content as dmesg_before, so quoting source: "If dmesg_after exists, it means that the system can be resumed from BIOS, so it's likely to be a graphics issue. Otherwise, it's not related to graphics and don't report it to freedesktop.org bugzilla." will try to set Enable "CONFIG_PM_DEBUG" for next test
tested with CONFIG_PM_DEBUG with core/processors/device dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after machine resume after few second, but mouse pointer is lost (not visible/not acting) joined dmesg_after
Created attachment 214301 [details] dmesg_after.txt output of dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after
