I installed Killing Time on a Windows XP (I know, but I don't have any other computer platform other than a Mac, and other older games I got from GOG have been working fine on it). And the graphics are a garbled mess (see pic). I don't see anything in the options to change the graphical settings, has anyone else had this problem with Killing Time and/or know how to fix it?

This game itself is a one big problem. At least PC version.

It uses some kind of launcher that theoreticaly should resolve messed graphics problem but instead of it this launcher creates even more troubles.

In my case it causes weird mouse glitch - game freezes for a couple of seconds after every click. For my mate game window isn't shows up at all - only black screen and sound. But these problems are in GOG Galaxy (so I've created a bug tracker report). Without Galaxy this game runs with messed colors.

I've tried to inform support about it some time ago but there is still no reaction. Too bad I can't do a refund now, so if you still can - you know what to do.

You can also try to PM JudasIscariot from GOG Team (the most responsive and helpful person on this forum) or create a support ticket.

I guess that this game is not so popular here and that's why we can wait for a proper fix for months.
