https://bugs.freedesktop.org/show_bug.cgi?id=98146 --- Comment #2 from Darek Deoniziak --- "Out of interest which compositor are you using?" Compiz 0.9.12.2. One more issue I forgot to mention, 5: while using HDMI monitor and pressing fn buttons to switch screens it sometimes gets buggy - the monitor plugged into hdmi divides itself every time when it happens, so I see main screen and it's smaller copy in left top corner, also screen doesn't react. Might be this the case of adding custom resolution to monitor in 10-monitor.conf? Monitor was missing at the begining 2k resolution, I've added it manually (monitor supports up to 4k res). Back about 4th issue: this mostly happens while running Steam, Blender and Atom text editor or Chrome. More native apps like Nautilus, gedit work great using DRI_PRIME=1. These all issues can be annoying sometimes, especially freezing while closing fullscreen, that's the killer one. -- You are receiving this mail because: You are the assignee for the bug.
