[Bug 1863763] [NEW] gnome-shell/Wayland on vmware/vmwgfx misrenders with large windows
Public bug reported:
There is a bug in mesa version 19.2.x where x>2, manifesting itself as
window contents in large windows on 4K display renders with an incorrect
vertical offset, making the desktop largely unusable for some customers.
The bug is fixed in latest 19.3 series and 20.0 rc series, but since
Ubuntu 18.04.1 still uses 19.2 series, a manual backport is needed.
Please cherry-pick mesa master commit
451cf228d53ba8f51beb3dcf04370e126fb7ccb6 ("svga: Fix banded DMA upload")
to fix the issue, alternatively switch to mesa 19.3 series.
Thanks,

[Bug 1690131] Re: display adapter not working with vmware
It looks like the logs you are posting are from a physical host running the modesetting driver on top of an intel kms driver. That's AFAIK not a VMware supported configuraion. Nevertheless you shouldn't see any rendering corruption caused by the VMware drivers in the guest. Could you post the vmware.log file for the VM as well as the Xorg.0.log file from the virtual machine and the output of "dmesg" from within the virtual machine.

[Bug 1560498] Re: Unity8 using vmwgfx_dri.so crashed in mir::graphics::nested::detail::DisplayBuffer::make_current() -> eglMakeCurrent() -> ... -> dri2_image_get_buffers() [platform_mir.c:138]
OK, So I tried to debug this on 17.04 with the mir demos.
What happens is that while the Mir server seems to run fine,
when the EGL mir clients import a surface from the mir server (using fds /
prime) they
typecast the XRGB surface from the mir server to an ARGB surface, which the
svga gallium driver doesn't like that and it returns an error.
That error is never caught in the mir platform EGL layer and when the
corresponding "bo" is dereferenced, the mir platform EGL layer instead
dereferences NULL, which is the error code...
So I'd say this is a combination of two Mir errors: One illegal typecast and
one failure to check
for errors.
As a side note, it would be possible for the svga driver to implement a
workaround and not error
in this case, but while real hardware may be more forgiving in this case, the
surface that the
mir client thinks is an argb surface will still be an xrgb surface and any
operation involving the
alpha channel will yield unexpected results so IMHO this needs to be fixed in
the MIR EGL layer:
Offending code: (platform_mir.c)
static struct gbm_bo *create_gbm_bo_from_buffer(struct gbm_device* gbm_dev,
MirBufferPackage *package)
{
struct gbm_import_fd_data data;
data.fd = package->fd[0];
data.width = package->width;
data.height = package->height;
data.format = GBM_FORMAT_ARGB; /* TODO: Use mir surface format */ <=
HERE!
data.stride = package->stride;
return gbm_bo_import(gbm_dev, GBM_BO_IMPORT_FD, , GBM_BO_USE_RENDERING);
}

The problem is I can't verify the bug is fixed in trusty because it doesn't show any obvious symptoms. This is probably due to different stack ordering of local variables compared to the trusty stack on precise.

[Bug 1365490] Re: ubuntu 12.04.5 broken on VMware
[Impact] A user might find Ubuntu 12.04.5 unusable on vmware because he would face a black screen after logging in. Although there is a workaround (disabling 3D) a user may have given up at that point. Backporting will help the user run the distro after upgrading, so I believe it's highly justified. [Test Case] On VMware Workstation 10, Install Ubuntu 12.04.5, preferrably using easy install. Boot the VM, log in. You'll see a black screen only. [Regression Potential] The bug affects a function that impots a shared buffer to the 3D driver. The function is completely broken by the bug. Even if the patch should introduce another type of breakage, the problem couldn't be much worse than it already is, and should be confined to the specific function in question. [Other info] Due to different stack ordering of automatic variables, the bug may or may not be visible depending on the C compiler and the level of optimization used. For example, if -O0 -g is used the bug is not visible on 12.04.5. I have not encountered any symptoms of the bug yet on 14.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365490 Title: ubuntu 12.04.5 broken on VMware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1365490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1293384] Re: Compiz CPU usage dramatically increased in Ubuntu 14.04
OK, I did som investigation, and it seems like even for the slightest change in a window, like a cursor blink, compiz performs a fullscreen swapbuffer, and in the case of multiple monitors, compiz performs a swapbuffer that spans all the monitors. I tried to install ccsm and disable all tweaks that could trigger this behaviour and revert to use GLX_MESA_copy_sub_buffer, but that didn't help much. Except if you start on a low resolution and change resolution to something higher. THEN compiz suddenly changes update and performs updates that are not quite that large. The only drawback is that those updates seem to cover also a number of unrelated areas that are not updated. Now needless to say this becomes very suboptimal in remoted virtual environments, and also it appears very suboptimal if llvmpipe is used.

OK, So I've finally been able to do a bit of testing with Ubuntu 14.04 If run without 3d support on llvmpipe, it's very CPU-hungry. A bit more so than Ubuntu 13.04 AFAICT. For Ubuntu on VMware this becomes troublesome primarily on ESX, but the problems were introduced with the drop of Unity 2D. I haven't dug thoroughly into why it hurts so much on ESX. Could it perhaps be that Unity / Compiz is performing full-screen flips when only a part of the screen is updated? Also we have severe performance problems when running fully 3D accelerated with workstation / fusion on multi-monitor setups. That's partly due to how the VMware device updates screens but Ubunut 14.04 stands out as particularly slow here.

However, the issue is, according to our testers present when running in 3D mode on ESX (on a slow llvmpipe-based GPU), but I guess in that case, Unity has no way of detecting that the GPU is slow, and hence runs with all effects enabled? /Thomas -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293384 Title: Compiz CPU usage dramatically increased in Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1293384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1293384] Re: Compiz CPU usage dramatically increased in Ubuntu 14.04
Yes. we were aware of the Unity2D vs Unity3D difference. However, there *is* 3D support on vmware (although sometimes slow) and part of the problem is that also with 3D enabled, Ubuntu 14.04 is slower than with 3D enabled on12.04, although we haven't quantified that yet, and we assumed that any improvements here could also be applied to Unity 3D in software mode But as you mention, the problem seems to be more complex due to the fact that many effects are already disabled in software mode...

[Bug 1293384] Re: Compiz CPU usage dramatically increased in Ubuntu 14.04
Hi! Thanks. I think we need to discuss this internally first. The reason is that sometimes the virtual GPU is backed by a fast physical GPU. Sometimes it's not, and it's only in the latter case there is a performance issue, in the fast case, we'd want all effects enabled. And also when the GPU is not enabled at all and compiz-on-llvmpipe kicks in, but as you say there's not much to be done in that case. Thanks a lot for your help. I'll get back to you next week. /Thomas -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293384 Title: Compiz CPU usage dramatically increased in Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1293384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not sure whether there's a way to raise the importance / severity of this bug, but according to VMwre QE, this severely affects the usability of Ubuntu 14.04 on ESX. /Thomas -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293384 Title: Compiz CPU usage dramatically increased in Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1293384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
