So I bought Gothic as part of the weekend sale and I'm disappointed to find out I'm suffering from the missing inventory pictures bug. I've checked this thread:
http://www.gog.com/en/forum/gothic/item_pictures_in_inventory_not_visible
And it seems to indicate that Gothic seems to have an issue with Radeon X1*** cards. The only solution seems to be trying different drivers.
I'm running the game on WinXP SP3 with a Radeon X1950 GT card using the 8.12 Catalyst drivers. If anybody knows what drivers would work or another work around for this issue I would be very greatful.
Thank you in advance.

I would just like to add that the problem is not only for radeon card, since I'm using an nvidia card and also can't see some invetory pictures...

I get the same problem on my NVidia card. It's a z-buffer issue. You'll notice when the inventory items disappear, it's because a wall or other object is getting drawn on top of it. While in inventory mode, use the mouse to move the camera, and you'll see the items re-appear as they are no longer covered by the object. I'm trying to figure out a way to get around this. It's annoying, but not crippling.

I have the bug and it is far, far from a game breaker, hardly impacts my game experience at all. I am really enjoying the game.

Does the issue exist on Radeon 1xxx GPUs only, or any GPU after that series? I have a Radeon 5770.

Also, "It's solved in the way that there is no solution..." is one of the stupider things I've read today. Thanks for the chuckle.

It's that series of cards only, which is why upgrading is being recommended.

I have an ATI HD3850 and the inventory and everything else works perfectly.

Thank you.

i got the game now, and see this in gothic.ini:

zInventoryItemsDistanceScale=1.3
; ... some rare grafic cards have a high near clipping value resulting in inventory items not being visible (esp. if you have the cursor focus on it)
; with entering a value above "0" you can scale the item distances from the camera in order to make the items smaller, but visible
; (e.g. with a value of 2.0 the items will be twice as far away from the camera)
; range: 0..1000. (default: 1.3)

I didn't need to change anything - it works on my system - but that .ini comment and related setting sound similar to the issue described in the topic here anyway. Curious. maybe someone with the issue can use this information to resolve the problem.
