Incorrect OpenGL/GLES drawing z-order in guest os

[djdron]

Views inside windows with OpenGL/GLES rendering appears to draw always on the top of all. This is really annoying because you can't see popup menus, etc. Also this OpenGL/GLES views somtimes "freezes" and not update 3D graphics inside it.

How to reproduce: Install Ubuntu x86-64 guest inside Windows 7 host. Install Guest Additions. Install Google Chrome browser. Follow some HTML5 web sites with WebGL (GLESv2) content (​https://chrome.google.com/webstore/category/home?utm_source=chrome-ntp-icon) Try to browse. FAIL.

Also look attached screenshots:

host machine configuration

gust machine glxinfo log

[83.manish@…]

I am also getting the same error.

Below is my configuration:- Host: Windows 7(64bit) Guest: Ubuntu 13.04 Virtual Box : 4.3.6.r91406 Guest Additions : Installed. Glxinfo logs : glxinfo.log (Attached) Host machine configuration : gpu_caps_viewer_report.txt (Attached)

Any idea how to fix this?

Please reopen if still relevant with a recent VirtualBox release.

While I cannot reproduce the issue with Chrome (is the site still using OpenGL?), I can definitely confirm that the underlying issue still persists, for example with glxgears as shown in one of the original screenshots

sudo apt-get install mesa-utils
glxgears

but also with many other apps that use OpenGL, for example visualizers for molecules (xcrysden[1], vmd[2]).

This is with VirtualBox 5.2.18, Guest OS Ubuntu 16.04.5 LTS, Host OS MacOS 10.13.6 (I've heard about this also from people with other Host OS's).

Happy to provide additional input on this issue - it currently forces us to disable 3d acceleration in VirtualBox, which obviously comes at a significant hit in graphics performance.

Same problem on the newer Ubuntu 18.04.1 LTS (guest).

Maybe some suspicious lines from /var/log/syslog will help?

issue on VirtualBox 6.0

[Leopold Talirz]

The issue persists on VirtualBox 6.0 with Ubuntu 18.04.1 LTS guest (now accompagnied by distortions of the background, see screenshot).

[Leopold Talirz]

For me, the issue has finally been resolved in VirtualBox 6.1. I'm now able to install glxgears, drag the window around + it correctly goes into the background when I select a different window.

VBox configuration: Graphics Controller VBox SVGA, 3d acceleration enabled

Guest: Ubuntu 18.04.3 LTS

Host: MacOS 10.14.6 (Macbook Pro 15" Mid 2015)

[aeichner]

Thanks for the report, the old 3D code was removed and we don't plan any fixes in that area for 6.0, please switch to the VMSVGA based 3D support and report any issues in that area, thanks! Closing as wontfix.
