Bug#1081957: libgtk-4-1: libgtk-4-1: vulkan renderer crashes on startup under kwin-wayland

[Zoltán Döme]

Yeah, 200% scale. It's also a laptop with AMD igpu + dgpu, so that could
also complicate things.

In my backtrace the vulkan surface handle passed to the driver calls was
0x0 which sounds invalid?

Michael's backtrace seems essentially the same to me, I just had no sources
on hand and used the debian debuginfod instance.

Cheers
Zoltán
