Nothing I've tried is stopping this from happening. I've tried fresh installs on each on my harddrives, I've removed every Divinity folder/file/registry. Not using any mods whatsoever. I've even tried pirating the GOG version and installing that but it still has the same problems.
You can still click on and interact with items/NPC's behind the tears but it's a pain in the arse trying to find them sometimes. Not all tooltips will show up and some NPC's won't be highlighted.
I have an inkling you are using an Nvidia GPU. I have another inkling you've made some changes in the Nvidia control panel. Try reverting to default, or disable any supersampling or transparency aliasing.
