<pre>When playing WoW for several hours, I notice that the game-play becomes
increasingly jerky over time. Once this effect has become noticeable, the game
takes longer to exit as well - often several minutes. There is no response to
either keyboard or mouse movements during this interval, although the box seems
to behave normally enough when eventually the (full-screen) game window
disappears and my desktop returns.
When I attached gdb to the X server during one particularly unresponsive
interval, I discovered that it was looping in DRI2DrawableGone:
0x00000000005732b4 in DRI2DrawableGone (p=0x1de81e0, id=1117964837) at
dri2.c:382
382 xorg_list_for_each_entry_safe(ref, next, &pPriv->reference_list,
link) {
This is with a Radeon HD4890 / 3.14.2 / x86_64, although the problem has
actually existed for several months.
