Segfault on Fedora 30.

[mopomi]

I am running Fedora 30 on a machine with 128 GB RAM and a GeForce RTX 2080 video card. I recently upgraded to a very high resolution and large monitor (49" 5120x1440). Since then, virtualbox will not start.

When I run on the commandline, I get the following error, before any graphical interface is displayed (i.e., before I can even try to boot a guest OS):

% virtualbox
(VirtualBox:33239): librsvg-WARNING **: 10:36:43.169: cannot render on a cairo_t with a failure status (status="invalid value (typically too big) for the size of the input (surface, pattern, etc.)")
Segmentation fault (core dumped)

I've used the Fedora package manager to make sure I have the most recent version available through that source (VirtualBox-6.0.12).

the most recent version is 6.0.14:

I'm also experiencing this using Linux Mint 19.3 / 5.3.0-28-generic. I've tried versions 6.0.16 and 6.1.2.

I'm using a Dell 49" monitor with a native resolution of 5120x1440. If I go into display manager and change the resolution to 3840x1080 or 2560x1080 it works just fine. When it fails the VirtualBox Manager has a non-updated window in the upper left corner with no frame and nothing in it beyond the previous desktop image.

This issue should be associated with QTBUG-77828 -- at least for my issue this appears to be the problem.
