[Bug 1150675] New: Is Intel 945 GME still supported?
http://bugzilla.opensuse.org/show_bug.cgi?id=1150675 Bug ID: 1150675 Summary: Is Intel 945 GME still supported? Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: i586 OS: openSUSE Factory Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: nt1277@gmail.com QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Created attachment 818117 --> http://bugzilla.opensuse.org/attachment.cgi?id=818117&action=edit The elements (polygons?) of the folding envelope of Gmail are distorted and flickering on Intel 945 GME Since a few weeks ago I experience some glitches on my notebooks with Intel graphics chipsets. I will attach a screenshot. One of my machines is an old 32 bit computer with an Intel 945 GME graphic chip, running an up-to-date 32 bit OpenSUSE Tumbleweed with XFCE. When I installed it in the beginning of this summer, it ran compiz very smoothly, but since an update, 3D acceleration has clearly visible and very disturbing quirks. These quirks become even more annoying when memory usage increases. The elements (polygons?) of OpenGL 3D objects are often misplaced, distorted or even flickering. I tried to revert to older kernel versions (5.0 and 5.1) from http://download.opensuse.org/repositories/home:/tiwai:/kernel:/5.*/standard/ , and it PROBABLY moderated the problems, but definitely didn't eliminate them completely. -- You are receiving this mail because: You are on the CC list for the bug.

Well, this sounds like a 32bit netbook from 2012? Maybe you can try to disable "Display compositing" in XFCE? -- You are receiving this mail because: You are on the CC list for the bug.

No, it's an even older machine from 2009. I'm a bit into retro computing. I currently use a non compositing window manager which works fine, but there are glitches in OpenGL accelerated components of the applications. -- You are receiving this mail because: You are on the CC list for the bug.

Since you were mentioning XFCE and Display compositing" is its default that was my first idea. Unfortunately driver regressions are always possible and the older the hardware the more unlikely it is, that these get fixed again. :-( You may want to give Mesa's environment variable a try LIBGL_ALWAYS_SOFTWARE=true -- You are receiving this mail because: You are on the CC list for the bug.

Well, I didn't even know that XFCE's window manager does compositing. You're right, it's the default, but I didn't notice it because it doesn't do any Compiz-like trick. However, I enabled some transparency in window handling, and I noticed that xfwm4 uses openGL indeed, but it runs very smoothly and without any gliches. Then I tried glxgears, which also ran with high FPS and without any problem, even when xfwm4 made it transparent. So 3D rendering is not entirely broken, only some functions of it, and the problem seems not to be in the kernel. The attached gmail glitch for example also occurs with windows compositing disabled. I'm afraid it's an upstream bug either in the X server or in Mesa. Thank you for the informations. -- You are receiving this mail because: You are on the CC list for the bug.

Anyway, whether you believe or not, Mesa 20 solved the problem. It works perfectly now. FIXED! -- You are receiving this mail because: You are on the CC list for the bug.
