you should allways install the graphic card driver by yourself, windows update won't be the best way and sometimes totally messes up the things. (re-) install the current driver version from amd / nvidia / whatever website and reboot the system. after this you should be able to play. ^^
this ist the current prontera-map in kRO, just updated to 28.02.17 and got the same map...
also for the snow, this was kRO, they seemed to enable snow in prontera somwhere in january and disabled it in february ^^
I'm working on something like this for my private emu-project... But there is only a base-support right now.
Any accurate info about kRO episodes would be helpfull here ^^ (Latest Commit: https://github.com/15peaces/15-3athena/commit/b550594f23368cda6d1395bf72746c40d3d4ec57)
I had the same problem on 2013-12-23 ragexe and was unable to remove them... I've read something about debug-numbers or something like this (don't know if it was here or on herc forums...). So I don't know if you even can remove these numbers? o.o (Currently using 2014-10-22 ragexe, so I cannot test it right now ^^)
the patch won't work in txt-mode.. I'm planning to fix this issue soon. Pleas follow it on github (btw. there was a update on this patch ^^):

this should be working on eAthena... maybe you'll need to patch manually:
