Important Bug in Unscaled HiDPI Support on Windows8.1/10 Guest

Reported by: DreamPiggy Owned by:
Component: guest additions Version: VirtualBox 5.0.0
Keywords: Unscaled HiDPI,GuestAddition,Windows8.1/10 Cc:
Guest type: Windows Host type: Mac OS X

Description

VirtualBox Version: 5.0 r101573(official release version)
Host Version: OS X 10.10.3 with MacBook 12`(Retina HiDPI 1280*800 default setting)
Guest Version: Windows 8.1 / Windows 10 but not Windows 8

What's wrong:

After installed VirtualBox GuestAddition(with build-in version or 5.0.0 RC1,RC2,RC3 or whatever the latest 5.0.1 test version),the Unscaled HiDPI Support was broken.The entire monitor image distortion where the mouse pointer are.Look at the screenshot(which means what I see from screen).

What I see:

http://img.hb.aicdn.com/732c6e18a2fd38e4f46b93fd678c9bb0dbfa64849196d-iV9kkv_fw658
But at the same time ,use the build-in screenshot(which means use the VBox toolbar option),everything looks OK.


What VBox screenshot show:
http://img.hb.aicdn.com/72dbce851d5a0d23713712e204d933a1a420ed2910c78a-UnofOO_fw658

What I do:

After installed the older GuestAddtion(VBoxGuestAdditions_5.0.0_BETA4,link here:  http://download.virtualbox.org/virtualbox/5.0.0_BETA4/VBoxGuestAdditions_5.0.0_BETA4.iso)
it works OK! But this GuestAddition may cause WPF-Application crash(include VS2015 or some Metro Apps),and the latest version GuestAddtion(VBoxGuestAdditions_5.0.1-101689.iso) also have this bug.So there are no way to keep both useable and Retina support...Therefore I think maybe some commits after that BETA4 reinsert this bug.....

What I guess:

Windows 8.1/10 use the new DPI-Aware API( https://msdn.microsoft.com/en-us/library/windows/desktop/dn469266%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396)
which may behave differently from Windows 8.
So this may be fixed by find the bug commit or add some special judgement code? I don't sure this may happen only in OS X Guest or All platforms.But i'm hopefully to fix this..

Attach are here.Include the VBox Guest and Host.

Add some new :

After disable the 3D Accelaration.Both 8.1/10 with latest VBox & VBox GuestAddition work well..

But sadly you can't enjoy the DirectX Accelaration speed..Everything works slow...

Hope to fix it to make both HiDPI 3D WPF-Application work well..

Having the same issue - Windows 10 Guest, on Mac OS X Host, When you switch it to Unscaled HiDPI, the graphics are all over the shop - it makes the guest unusable, but I would really like the full resolution in the guest if possible, with 3D acceleration on.

If you turn off 3D Acceleration, then the unscaled mode appears to work.

Replying to GeoffO:

Hey..Is there some ways to fix this issue? Or have the new beta version VB fix it?

Same as #14231

This is still a problem with 5.1.16 -- have to disable 3D acceleration as a workaround, which makes performance/responsiveness of the VM not that great. Any chance of someone looking into this?

(And yes, this covers the same issue as #14231, so they should probably be merged; I'm bumping this one because of the better screenshots.)

Still a problem with 5.1.19

comment:7 Changed 3 years ago by BZ

Still present in 5.1.22

comment:8 Changed 2 years ago by smak

Same exact issue, still present in 5.1.30. You can't enable 3d acceleration AND Unscaled HiDPI mode together. It's one OR the other. Speed, or fuzziness, choose one.

Host: OS X 10.13 High Sierra Guest: Windows 10 N Virtual Box: 5.1.30 r118389
