16574	Win7 Pro lockup using WDDM and Aeroglass Decorations	drankinatty		"All,

  I have openSuSE x86_64 host and Win7 32-bit guest. I experience regular lockups (guest and host) when using WDDM and Aero on Win7. The strange part is when the Win7 crashes or locks up, it will also lock the host desktop (kde3, i3 or fluxbox). I know that WDDM is experimental, but given then number of ""Hey, I'm using it and it works great"" howtos and tutorials, I would expect it to be a bit more reliable than I am seeing.

  I have the virtualbox.org rpms and extension packs installed, along with the guest additions, e.g.:

Oracle_VM_VirtualBox_Extension_Pack-5.1.18.vbox-extpack
VirtualBox-5.1-5.1.18_114002_openSUSE132-1.x86_64.rpm
VBoxGuestAdditions_5.1.18.iso

  I am running the guest on hp_8670W laptop, i7, quad core, hardware virtualization, 8G of ram. Guest is allocated 1 CPU, 2560M Ram, 256M Ram to display with 3D and 2D video acceleration checked.

  The lockups are semi random. Enabling Aero works fine. The desktop looks great, but anywhere from 30 seconds to 5 minutes later, all CPU/Network/etc. indicators in the status bar go red and the guest is locked. The mouse and keyboard are also trapped in the guest and the host desktop is locked (well, left without any input devices) as well.

  When I reinstall the guest additions, removing WDDM, and drop back to the basic Win7 Pro desktop, all is fine. I can run all day/night without issue. (64M Ram for display, 2D acceleration, no 3D.)

  I'm not sure where the bug is, but I would sure like to help get it fixed."	defect	new	WDDM	VirtualBox 5.1.18				Windows	Linux
