I have problem with interface in game and menu. The menu is constantly highlighted (like when you click when selecting options e.t.c) and interface when playing become transparent. I will show this on screenshots below. Also some video options are "un-clickable".
More interesting part is that the game had worked properly earlier and this bug happened to me few times but only after 2 or more weeks after instalation (so I just uninstall it and install again for some time). However now this bugs shows up instantly after installation. I've tried running game after clean installation without patches, I've tried running game with all the patches, critical rebuild and community patch 1.70, 1.71, I've installed hundreds of modules, mods and other stuff and I've tried to run the game without even one mod, I've tried install the game in my custom installation folder and in the way shown on this forum (Windows 7 installation), I've tried running it as an administrator with compatibility mode for windows xp servce pack - nothing helped, this extremely annoying GUI disappearances and highlighted menu drives me crazy. I have Diamond Edition of the game from GOG.
Notebook Samsung NP550P7C, Windows 7, 6 GB RAM, up-to-date drivers, graphics card GeForce GT 650M.
Also all visual effects and creature animations (in creature properties/viewer) in the toolset are extremely speed up. I don't have to add that all of these bugs occurs simultaneously, I've never seen a single one on it's own, only all at once.
