Hi,
I use Minetest nightlies on Ubuntu 14.04, with Unity.
Since a couple days, the startscreen, where Parameters are set, Servers are chosen, etc is unusable, hence it uses a fontsize which is extremely small. The dimensions of the screen are not changed. After logging in (by chance) everything ingame works as normal. Just, to set up access to a network server or starting a new game just does not work at the moment, due to the enreadable fontsizes.
Cheers, (or "Hils" as the Norwegians say )
and many thanks for your otherwise brilliant work!
Stefan
