Plasma-emojier is very slow / makeQtWrapper is accidentally quadratic?

sort-of debugged maybe?

That’s the slow syscall:

23:43:01 ioctl(14, _IOC(_IOC_READ|_IOC_WRITE, 0x46, 0x2b, 0x20), 0x7fff648c1e40) = 0 <1.818853>

Apparently this has something to do with my nvidia video card, and it looks like what’s happening is that GPU driver is being unloaded:

(this is mostly a guess at this point, but the theory looks sound).

Not sure what’s the problem though – the fact that the driver is unloaded, or the fact plasma emojier needs to poke nvidia driver at all…
