I tested with 3d-acceleration disabled:

NO MORE UPSIDE DOWN ERROR !!!

Thanks for the hint very much!!!

Are answers to this these questions are helpful after the finding 3D-acceleration the culprit?

(The guest app is a very conservative tax tool. It runs fine under native Windows.)

I've upgraded VB to 6.1.2. This didn't resolve the problem with 3d-acceleration and upside-down-text.

Upgraded VirtualBox and guest additions to 6.0.16 and still seeing the same problem: Photoshop images are upside down when switching the Graphics controller from VBoxVGA to VBoxSVGA.
Can't upgrade to Vbox 6.1 as it drops VBoxVGA driver.
Something that may help you to debug: when using the Photoshop transform tool (CTRL+T) the image is temporarily flipped on the correct side.
Vbox log for 6.0.16 is attached.
Please fix this bug soon.

Have any of you opened a Bugtracker ticket on this? If there is anything to fix in Virtualbox to solve this, there would be the place to start asking for fixes (politely). We are just fellow users here, and there appears to be nothing in the logs that would blatantly indicate why this would be caused by Virtualbox. Nonetheless, it could be that there's no log entry where the error is happening.

If you have an afternoon and a spare hard disk, try a fresh install of your host OS, the exact same version of host graphics drivers, Virtualbox, and copy over the guest, and see if the OpenGL is still flipped. Also try a fresh guest.

Just searched the bug tracker and couldn't find it, here's the new ticket https://www.virtualbox.org/ticket/19237

Looks like a good ticket, htrex, with a log & a link back to here.
Let's see what the devs can do.

VBoxVGA is present in my 6.1.2 Virtualbox (Mac Host)

6.1.x actually drops 3D acceleration for the VboxVGA video card. The video card itself is still there and must remain for more long-in-the-tooth supported guest OS's.

I think I may have found a solution. I had VBoxSVGA graphics controller chosen and 3D Acceleration box checked and it happend than in some 3D OpenGL programs the image was top-down reversed. I should also note that VirtualBox Additions were installed with Direct3D Support checked.

I tried to disable 3D Acceleration and image was no longer reversed, however 3D rendering performance was quite poor.

After reinstalling the VirtualBox Additions with Direct3D Support cleared, the image in 3D OpenGL programs not longer is reversed although the VBoxSVGA graphics controller is chosen and 3D Acceleration box checked. Within the 3D OpenGL programs the performance is now as expected.

To sum up, reinstall the VirtualBox Additions and assure that Direct3D Support is disabled, then in Display tab of VirtualBox machine settings select VBoxSVGA graphics controller and check 3D Acceleration.

@jskraba, how could you install guest additions with Direct3D support disabled?
On a Linux host Windows 10 guest, I've tried to do it and the relative checkbox in Vbox Additions installer is always selected, greyed out and unchangeable, no matter if I enable or disable VBoxSVGA graphics controller 3D Acceleration in the virtual machine settings, I couldn't uncheck it.

Also, when installing the VirtualBox Additions, if you look at the Direct3D support option description on the right it says "Enables Direct3D and OpenGL acceleration..."

Are you sure that OpenGL is accelerated on your guest, or you're seeing placebo effect?
