ModEdit; related ticket: #18819: 3D Acceleration not working in 6.0

---

I was using VB 5.2.22 on Win7 host with Win10 guests for a long time. I set the guests to use 3D and 2D acceleration and never noticed an issue.

I rebuilt my host to Win10 v1709, same hardware including the NVIDIA Quadro GPU. I installed VB 6.0.10, created new VMs, and then quickly ran into the shared folder crash, so backed down to 6.0.8.

When I set the Win10 guest to use 2D and 3D (256MB), I have graphics issues. The most notable is that videos won't play in WMP or VLC (audio only, no image shown). There is also a lot of flickering and choppiness in the OS UI. If I toggle off 3D, then videos will play and other OS UI animations are smooth again.

Is this a known bug with a report? (I didn't see one in the bug tracker...)

EDIT: clarified what I mean by "videos won't play", uploaded log files

We need to see a complete VBox.log, from a complete VM run, where the problem occurs:

• Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

same problem:
opengl is glitching, directx not working (maybe it is initializing but not rendering).

Sacratis, have you had a chance to look at this one? Any update on it?

I had same problem using 6.0 for a win guest on linux host with nvidia GeForce GTX 1050 Ti

Thank you, develo and navarobot, for posting your logs.

I submitted bug report #18819, https://www.virtualbox.org/ticket/18819.

Did you try if switching between VBoxSVGA and VBoxVGA makes a difference? If your problem only happens with VBoxSVGA it might be the same one as I have. My logs are here: viewtopic.php?f=2&t=93969&p=453874#p453874

I did another test, using Linux host and linux guest ( of course 3d accel seems to be recognized only with VMSVGA that is default for that guest ); 3D accel recognized correclt but the problem happens in this case too ( attached screenshoot, from linux just hit meta key to open activities window )

I don't know if the problem is related to vbox machine or vbox guest additions, btw its can be tracked expecially when transparency tiles are on the screen.

UPDATE: tried 6.0.14 but no difference ( mouse cursor small, background clipping ) and another thing I noted is that html5 3d tests results Y flipped as attached screenshoots

to test HTML5 3d check follow url ( http://www.kevs3d.co.uk/dev/shaders/waves2.html )

This looks like the same clipping being reported in the other thread here:

Video playback should work on Windows hosts with the latest 6.0.x revision 134477 Could you please try the latest build from https://www.virtualbox.org/wiki/Testbuilds
Both the guest additions and the host package must be updated.

The upside down texture in the HTML5 3d test has been fixed in 6.0.x revision 134780
See https://www.virtualbox.org/wiki/Testbuilds

thanks,
I confirm that 6.0.x revision 134780 fixed upside texture problem,
while random rectangle regions overwritten with invalid content and small mouse icon still occurs.

devel0, please attach VBox.log and, if possible, a step be step instructions on how to reproduce the "random rectangle regions overwritten with invalid content and small mouse icon" issues.

sure, vboxlog.zip attached

steps to reproduce:

• start a win10 guest on a linux host
• when win loaded mouse cursor will go small ( can be viewed from random-rect1.png )
• start chrome
• move mouse cursor over some bookmark toolbar icons and a black background rectangle appears containing icon where mouse is over at that moment ( aspect ratio arranged in this case to height of toolbar itself ) see random-rect1.png

note: icon bitmap shown in black rectangle ( random-rect1.png ) appears when mouse move over calendar icon that can be seen from random-rect2.png when mouse move out from the toolbar
