guest windows distorted in seamless mode works on 5.2.2 (no such problems on 5.1.30)

[Walter Lapchynski]

STEPS TO REPRODUCE

1. Using Kubuntu Trusty host, Create XP VM in ≤ 5.1.30. Seamless mode should work fine (see expected results below).
2. Upgrade to 5.2.2.
3. Boot XP guest.
4. Switch to seamless mode.

EXPECTED RESULTS

1. Guest desktop disappears.
2. Host window decorations disappear.
3. Space is drawn on the host desktop for the guest windows.
4. Guest windows act like host windows, responding appropriate to movement, e.g.
5. Guest windows appear normally.

ACTUAL RESULTS

All of the above assumptions are correct except for the 5th one. The space is drawn, the windows act normally, there are no other decorations, but every guest window is a visual nightmare. See attached screenshot.

NOTES

• Host is Kubuntu Trusty running the 4.2.0-42-generic kernel and is fully up to date and restarted.
• Tested with versions from the repos at download.virtualbox.org: 5.1.30-118389~Ubuntu~trusty and 5.2.2-119230~Ubuntu~trusty. In both cases, the expansion packs and guest additions were updated accordingly.
• Guest video memory is maxed out.
• Turning acceleration off, enabling both 2D/3D or one or the other had no effect.
• Initially the guest was using multiple monitors. Disabling the virtual screen had no effect. Lowering the number of monitors to one had no effect, either.
• Full screen, scaled, and normal modes all function appropriately.
• VM has been running for years with no problems.
• Logs are attached. You should see the switch to seamless at 0:00:48.457777.

Oh? Invisible windows are not the issue over here. Or are you saying that wherever you see invisible windows if you toggle the view mode you see it, but with a distorted image?

[matthewls]

yeah, the places where windows should be are sometimes black rectangles, sometimes filled with e.g. lines.

And also running KDE host (mint 18.2)

[Socratis]

matthewls, please do not post/wake up every ticket that has graphics issues. Not all graphics issues are the same. I will not be duplicating my comment in the other tickets that you just commented as well...

[matthewls]

Sorry about that, I'll refrain too. No bad intent, only hoping to help VB folks gain a fuller view of problems with seamless windows under KDE plasma--what I suspect has one or only a few causes. But you are correct,that could well be wrong.

here's a screenshot (mlsscreenshot.png). VM guest windows 7 64 in seamless mode after pressing the windows key. the taskbar is invisible. Host Mint18.2KDE, plasma 5.11.3, QT 5.9.1, kernel 4.14.3 VB 5.2.3 r119337 qt5.6.1

I am seeing the same issue. Upgraded to 5.2 today and now if I go to seamless mode the open guest windows are present but have garbage as content. Switching back to normal mode and the window content displays correctly.

Upgraded using VirtualBox-5.2-5.2.2_119230_fedora26-1.x86_64

ThinkPad T440p running Fedora 26 with Cinnamon as UI. Kernel 4.13.16-202.fc26.x86_64

Problem shows up with following guests on above system: Windows 7 Pro 64 bit guest, Windows 7 Pro 32 bit guest, Windows XP guest

Will attach before and after screen shot showing what happens when switch to seamless mode.

I believe I'm having the same problems with Ubuntu 16.04.3 and VirtualBox 5.2.4 (host) and Windows 10 (guest). I can provide more screenshots and information if so needed.

[sanderv]

Seeing the same results in Ubuntu 17.10, both with Xorg and Wayland.

[Bj]

Same result in an Xubuntu 14.04 host, using VirtualBox 5.2.6 r120293 and a Windows 10 guest.

[Bj]

Sorry, that should have been "same result in an Xubuntu 16.04 host." I'm not that far out of date....

[red baron]

Same issue in Linux Mint/Xfce 16.04 host, Windows 7 client. Upgrade from Virtualbox 5.1.x to 5.2.6. All application windows in seamless mode do not appear.

[maxxsch]

Same issue in openSUSE Tumbleweed 20180208 (and on previous versions too). Using Windows 7 guest and VBox 5.2.6-2.3.

Is this a duplicate of #17304? Does the solution there work?

Yep. Running 5.2.7 r120822 works just fine. Feel free to close this.
