Follow-up Comment #4, bug #35757 (project screen):

I have an idea, but I am not sure if I am not completely wrong. When is screen
calculating resize it uses current cursor location, but I think that it should
use the position where the cursor was before entering altscreen. I have tried
this small modification and segfault is gone.
