help ! see through items, textures are being strange ;-;

[ChickenPots]

Items are appearing like this http://prntscr.com/9m60ij , http://prntscr.com/9m60vz , http://prntscr.com/7quurz

All and any items that are see through appear like that on my screen no matter what graphics level I set it to.

They look very broken with triangles and look like they have alpha issues but thats not the case for everyone since I had my friends screenshot what they see on their screen in comparison to mine.

i see this: http://prntscr.com/7qum4g
my friend sees this: https://gyazo.com/66b2e30a91a3b7dabfdc501aff1ebabb

Second issue im having is on windlight with blur multiplier for the water settings, I used to be able to create pretty photos with it but now it just becomes like this http://prntscr.com/9m62wy

At first I thought maybe its my graphics drive, but i updated everything and checked and nothing has changed....

For more information I'm on an iMac using the firestorm viewer. http://prntscr.com/9m669x

*edit: it wasn't like this before?? I've always been on my iMac using the firestorm viewer and nothing like that happened... until i updated the firestorm viewer I think....... i can't remember when this started, it's been a while now...

Please help !!

Thank you !!

The broken triangles effect on the  mesh objects where the textures have transparency looks like https://jira.secondlife.com/browse/BUG-8801

It's Mac specific & it will reproduce on all graphics settings on all up to date viewers. There is no workaround that I know of.
