Well. Now it's really weird :)
It seems that I have unstable result with just plug/unplug my "espruino with screen" to power. And sometimes I can see everything on my screen just perfectly, sometimes.. well.. nothing. And sometimes very-very light. I'll continue to investigate, but it seems that roots of this problem is somewhere with SPI and screen itself. And it's completely new field for me, first time playing with SPI and screen :)
And even delay with screen init, while quite obvious, didn't came to my mind :)
I can post my code, but it's very similar to the one that you can see on the top. The only difference I see is where SPI1.setup() located. Mine - outside of onInit().
