libgdx/lwjgl jerkiness rendering meshes / texture regions

I am rendering some textured cubes along with libgdx’s TextureRegion (which are essentialy textured quads) and I’m seeing some jerkiness when the camera moves. It seems like te textures are “shaking” a little as the camera moves. It’s a little difficult to express in words, but sometimes it seems like some pixels are blinking or shaking.

The only thing moving is the camera, the objects don’t change their position.

The texture for the cubes are 128x128 areas on a 512x512 png texture (the bricks in the image). The objects like the windows and purple thingie are TextureRegions from a 1024x1024 image.

Any ideas on what might solve that ?
