[i915] screen update problem in blender 3d (7.3->7.4 regression)

[inoremap]

After updating the packages libgl1-mesa-dri and libgl1-mesa-glx from version 7.3 to 7.4 blender-3d became wrong to draw the contents of the window, and there are no icons on the buttons. Problem is reproduced on a computers with ubuntu 9.04/i386 with video intel i915, and ubuntu 9.04/amd64 with video intel i945 using EXA and UXA acceleration methods. After replacement libgl1-mesa-dri and libgl1-mesa-glx to version 7.3 problem disappears.

Please give the exact version numbers of both the good and bad packages you tested.

Also, are you familiar with bisection? To find the bug it will be necessary to do this to isolate which patch caused the failure.

After installing
dpkg -i libgl1-mesa-dri_7.3-1ubuntu3_amd64.deb libgl1-mesa-glx_7.3-1ubuntu3_amd64.deb
blender works fine.

on other computer libgl1-mesa-dri_7.3-1ubuntu4_i386.deb and libgl1-mesa-glx_7.3-1ubuntu4_i386.deb are also working fine, but now I can not find them on the mirrors to check

I checked again, problem disappears after replacing only one file /usr/lib/dri/i915_dri.so to i915_dri.so from package libgl1-mesa-dri_7.3-1ubuntu3_amd64.deb

I have the same problem with an i965 chipset and all OGRE3D applications. Switching back to libgl1-mesa-dri_7.3-1ubuntu4_i386.deb causes the problem to go away.

I'm experiencing this problem too

ubuntu 9.04/386

video-intel 2.6.3

Mesa DRI Intel(R) 965GM GEM 20090326 2009Q1 RC2 x86/MMX/SSE2

updating to mesa 7.4.1 from xorg-edgers completely solves the problem

As I run an i386 computer, search for the

libgl1-mesa-dri_7.3-1ubuntu3_i386.deb

an fixed the problem. I think that my video card is an i915, so:

unpack the file
copy all the files in ~/libgl1-mesa-dri_7.3-1ubuntu3_i386/usr/lib/dri to /usr/lib/dri as root

And now I'm Happy Blending !
