VBoxSVGA OpenGL upsidedown

[htrex]

I'm seeing a problem where Photoshop shows images upsidedown when using VBoxSVGA instead of VBoxVGA.

On the forum there are users seeing the same problem with various apps and environments: ​https://forums.virtualbox.org/viewtopic.php?f=2&t=92944

VBox Log where the issue occoured

[some like it not]

Problem occurs on 6.1.2 with VBoxSVGA with 3d-acceleration enabled. It does not occur with VBoxSVGA with 3d-acceleration disabled.

Please have a look at this other workaround found by jskraba: ​https://forums.virtualbox.org/viewtopic.php?f=2&t=92944&view=unread&sid=367ec26c798a423e38a3771ca2c4fd54#p468831

The issue seems related to Direct3D, not OpenGL. Hope this helps to catch the bug.

About jskraba comment, I've tried to follow the workaround he found, it doesn't work for me. Details here: ​https://forums.virtualbox.org/viewtopic.php?f=2&t=92944&view=unread&sid=367ec26c798a423e38a3771ca2c4fd54#p469042

I can confirm the same issue is happening when using Virtualbox 6.1.4

Confirm the bug for VirtualBox 6.1.6
Host: Ubuntu 19.10
Guest: Windows 7 (3D VBox Driver Installed)
VBox Driver: VBoxVGA + 3d-acceleration enabled

I tested to run Windows 7 without 3D-Driver installed, as in comment 2 suggested, but has the effect the program to test (Minecraft) to fail, complaining no OpenGL support.

See previous image and log

I can confirm the bug for VirtualBox 6.1.6 Host: Ubuntu 18.04 Guest: Windows 10 VBox Driver: VBoxSVGA (3d enabled)

Photoshop CC is still unusable due to misplaced image rendering with huge artifacts.

I can confirm this in VirtualBox 6.1.10 (Fedora 32 host, Windows 10 guest, vboxsvga + 3d acceleration). Testcase: ​https://yadi.sk/d/JX-O6ZK2TPtaqA It's a simple Qt qml program that displays an image with text. When started in VirtualBox the test is mirrored vertically. Qt I use uses ANGLE so in my case this seems to relate to Direct3D.

Cura running on Windows 10 on VirtualBox 6.1.12

I can confirm this very annoying problem.

I see this in 2 different configurations. Always Windows 10 Pro as Guest. Easy to reproduce with Ultimaker Cura (tried versions 4.6.1 and 4.6.2). Download Ultimaker.Cura-4.6.1-win64.msi from ​https://github.com/Ultimaker/Cura/releases/tag/4.6.1

My host systems are OpenSuse LEAP 15.1 64bit with VirtualBox 6.0.22_SUSE r137980 and OpenSuse Tumbleweed 64bit with VirtualBox 6.1.12_SUSE r139181

3D is activated (and needs to be to run Cura). Tumbleweed uses the open source AMD drivers for the Radeon rx580 graphics card (MESA 20.1.2) LEAP 15.1 runs on a Lenovo T450s notebook with Intel driver from MESA 18.3.2

The problem is still present in VirtualBox v6.1.18

Problem visible with host Ubuntu 20.4 (Virtualbox version 6.1.16_Ubuntu r140961) and NVIDIA driver 460.73.01, guest Windows 10 20H2 and Vectorworks 2020

[PrintoBoi]

This problem is still present with VirtualBox v6.1.22 As long as 3D-acceleration is enabled I am having the Cura environment upside down and fonts all gibberish and unreadable, and If I turn 3D-acc off it simply gives an error not being able to launch Cura. (Using Win 10 for both host and guest OS)

[rbalint]

Could this please be fixed? This issue makes VirtualBox almost useless for many use cases involving Windows Guests on Linux hosts. :-(

[abadono]

This is an issue for me as well as of version 6.1.30 on an arch linux host using an Intel HD Graphics 630 card for a Windows 10 VM. Turning off 3d acceleration "fixes" the issue but then programs are unuseably slow.

[cmccarron]

I can confirm that this is still and issue in VirtualBox 6.1.32. When using the Rockwell ViewDesigner v8 Emulator this issue is causing text to flip upside down and graphics to appear mirrored.

[cmccarron]

When Direct3D is disabled, the ViewDesigner v8 Emulator works without any issues.
