It spends 2.04 seconds waiting while opening /dev/dri/renderD129. 
(The strace below is showing timestamps in -ttt format: secs and usecs
since epoch.)

So the googles tells me that /dev/dri/renderD129 is a device for directly
accessing the graphics card. That's about as far as I got.

Settings / System / System details tells me I have:

    graphics: Intel® UHD Graphics (TGL GT1)
    Graphics1: zink Vulkan 1.4(NVIDIA GeForce RTX™ 3060 Laptop GPU (NVK GA106))

I haven't installed the Nvidia drivers.
