Moving any X window around is very sluggish, and text message output to exp= osed xterm chews 100% CPU. For example, doing a large compiling from a xterm, wh= en xterm in covered by another window, CPU is used only by the compiler; howev= er, when this compiling xterm is exposed (can be seen), system becomes slow and= top shows that xterm takes 100% CPU on one core. Playing video on firefox does not have much performance issue. It is not clear if this is a xterm issue or nv driver issue in xorg-7.7_x b= uilt under FreeBSD. The xorg-7.5 (xorg-server 1.7.7 from 8.4-R) works very well with GeForce 210 card, and X from the latest Ubuntu release 16.04 LTS (xorg-server-1.18?) al= so work well on this video card. --=20 You are receiving this mail because: You are the assignee for the bug.=
