18956,[VBoxSVGA with 3D] Graphics corruption in some programs,cremor,,"When I configure my Windows 10 guest to use VBoxSVGA with 3D acceleration I get corrupted graphics in some programs.
I'll attach a two files that show the problem:
1. A screenshot of Microsoft Excel where the horizontal scroll bar isn't shown correctly.
2. A gif animation that is a screen recording of my guest showing another gif animation in the Windows photo viewer. I'll also attach the original gif so you can compare the two. As you will see, the screen recording shows a completely broken animation. In some frames there is even a printer symbol visible that shouldn't be there.

Note: I think this is different from the existing tickets about white/black/transparent boxes in applications. I don't get those, so I usually can use the programs, only sometimes these graphics corruptions happen.
