Help me fix a few issues please

Hi there, As I’m finilizing my project I’ve got some last issues that need fixing.

1 - specles on the curtains
2 - frosted glass renders weird, especially around the edges
3 - the lighting close to the lightstrips are noisy compared to the rest of the image.

Please help me get these issues fixed before continuing to the final stage.
Thanks!

Might be better if you posted the setup of those 3 materials, so we can rule out any weird shader settings. Better to post a mat file with those 3 in it, no need for the actual bitmaps only the nodes. (curtain, frosted glass, interior wall)

I think you have to bright lights and to reflective materials.
