Unfortunaly, I don't know: I installed mayavi2 quite recently, but I was already using xserver-xorg-video-intel/2:2.2.1-1 from unstable. Then I upgraded from version 2:2.2.1-1 to 2:2.2.1-2, but those two revisions do not seem to differ too much as far as upstream code is concerned (at least, a glance at the Debian changelog seems to indicate only packaging modifications). > This was the > first intel driver in testing with EXA 2d acceleration enabled by > default instead of XAA. I can confirm that I am using EXA 2d acceleration: # grep -i exa /var/log/Xorg.0.log (==) intel(0): Using EXA for acceleration (II) Loading sub module "exa" (II) LoadModule: "exa" (II) Loading /usr/lib/xorg/modules//libexa.so (II) Module exa: vendor="X.Org Foundation" (II) EXA(0): Offscreen pixmap area of 19660800 bytes (II) EXA(0): Driver registered support for the following operations: (II) intel(0): 0x00032000-0x00041fff: exa G965 state buffer (64 kB) (II) intel(0): 0x00740000-0x019fffff: exa offscreen (19200 kB) > > Could you try adding > Option "AccelMethod" "XAA" > to the Device section of your xorg.conf in case the problem is EXA related? I added this option and restarted the X server. Let me check if I am actually using XAA acceleration: # grep -i xaa /var/log/Xorg.0.log (**) intel(0): Option "AccelMethod" "XAA" (**) intel(0): Using XAA for acceleration (II) Loading sub module "xaa" (II) LoadModule: "xaa" (II) Loading /usr/lib/xorg/modules//libxaa.so (II) Module xaa: vendor="X.Org Foundation" (II) intel(0): Using XFree86 Acceleration Architecture (XAA) (II) intel(0): 0x01950000-0x0195ffff: xaa scratch (64 kB) Yes, I am. Unfortunately I *can* reproduce the bug with XAA acceleration, as well: I still get the undesired fake transparency effect... :-( Hence it seems that the bug is *not* EXA related. > > Also, could you check whether the problem still occurs with latest > xserver-xorg-video-intel (2.3.0 is in experimental, and 2.3.1 will enter > unstable soon)? I hope I'll find the time and test version 2.3.1, as soon as it gets built for the amd64 architecture. > > thanks, Thanks to _you_ for your kind assistance! ;-) -- http://frx.netsons.org/doc/index.html#nanodocs The nano-document series is here! .....................................................
