I have installed 1.4 and noticed a great bug in planetary screen.
After 1.4 portraits of planetary improvements are totally messed up it seems like there is an overlapping between terrain portrit and improvement portrait.
I have no mod on gc2 i have just changed portrait of minor races so i don't think it is a reason of my messed up portraits of planetary improvemnts.
These are my specs:
AMD 3500+
X800XT
2 GB RAM
200 GB HD
