[SOLVED] Cura: garbled UI under wayland, sway, and nouveau

I'm trying to run Cura, but when loaded, I see the splash screen followed by a completely garbled/transparent window.

It looks like this:

I'm running Arch (up-to-date) with Wayland, using the Sway window manager and an NVIDIA graphics card using the Nouveau driver.

> uname -r
5.0.5-arch1-1-ARCH
> lspci -nnk | grep -iA2 vga 
00:1f.5 Non-VGA unclassified device [0000]: Intel Corporation 200 Series/Z370 Chipset Family SPI Controller [8086:a2a4]
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (2) I219-LM [8086:15b7]
	DeviceName: LAN (AMT)

	Subsystem: NVIDIA Corporation GF106GL [Quadro 2000] [10de:084a]
	Kernel driver in use: nouveau

21:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GL [Quadro P1000] [10de:1cb1] (rev a1)
	Subsystem: Hewlett-Packard Company GP107GL [Quadro P1000] [103c:11bc]
	Kernel driver in use: vfio-pci

I'm using the latest version of Cura,

> cura --version
Using Wayland-EGL
cura version: 4.0.0

Running it in debug mode doesn't give any obvious (to me) errors:

cura --debug &> out.txt

... gives this output: out.txt

The rest of my applications work fine, as does `glxgears`.

Any ideas where I could start to further debug this issue?

Re: [SOLVED] Cura: garbled UI under wayland, sway, and nouveau

Ok this was my fault -- I had the environment variable `QT_QPA_PLATFORM=wayland_egl` set, which forced cura to use a backend it doesn't support, rather than x11 via xwayland.

Deleting that environment variable, or setting QT_QPA_PLATFORM=xcb fixes things. Whoops! Cheers!
