I've just updated to 5.1.4 but my guest VMs will no longer resize to take up the available screen space in the host's window. Is anyone else seeing this problem?

Previous behaviour: Guest BIOS boot screen was in the middle of a large window, with the status bar at the bottom of the window.
New behaviour: Guest BIOS boot screen is in the upper-left of a large window, with the status bar just below the guest's content, and the other 90% of the host window is just random content from whatever happened to be showing there before.

Previous behaviour: Loading a guest OS with the guest additions installed would resize the guest to take up all available space in the host window.
New behaviour: The guest OS resizes and uses up 100% of the available width, but only 60% of the available height, with the lower 40% of the host window again displaying whatever random content was there before.

As I move windows around over the top of the VirtualBox window, bits of them are left behind in the extra space.

Have there been any changes to VirtualBox that might be causing it to stop making use of all the screen real estate allocated to guest windows?

I'm running 5.1.4 under Arch Linux with the AwesomeWM window manager.

What is your host OS, Kernel and Video card.

I had some early problems similar to this, But I'm having trouble remembering what I fixed.

Thanks for the reply. OS is Arch Linux, kernel 4.7.2 64-bit, and Intel onboard video with the default framebuffer driver (not using xf86-video-intel because it leaks memory too badly).

I'm running Manjaro (Arch) on 4.4.19-1-MANJARO (LTS),

I do use xf86-video-intel Version 1:2.99.917+697+g12c14de-0.1, (manjaro repositories) with no obvious memory leaks.
I have much of compositing bling turned on and the performance is more than acceptable. If its leaking, I've not noticed it. The machine runs 24/7 so you would think it might be a problem, but I'm not seeing it.

Same here.

Initially it works for one or two times but then it stops. Once it stops resizing there is also nothing appended to the logs anymore.
So it seems the window doesn't detect the window resize event anymore and thus it's not passed on.

I notice your log says 2D video accelleration is disabled. Any reason for that?
Also How much video memory did you allocate to the Guest? I know I initially had mine set way too low
and now its at 70 meg, and mine resizes nicely.

Also, Do you have remote display enabled?

Oh, and you are in the wrong forum section for a windows host, this section is for Linux Host.
but I suspect you are trying to cover all bases.
