Paper ink animation flickers - polymer

I seem to come across this issue on two of my projects. I have paper ink animations on checkboxes, which I have not altered the css. and the ink animations seem to flicker when I click the checkbox. The demos dont seem to do this.
Has anyone else come across this issue?
Thanks,

Bootstrap collapse animations disabled - when loading webpage at work

This is quite an unusual one, and I had no luck googling this issue.
Short version - I've created a basic webpage for my work, to streamline some tools into one place, which works differently when I open it at work, compared to when I open it at home.
Details - When I've designed it at home, I'm using a lot of hide/unhide content (bootstrap4 collapse buttons), which unveil content with a nice simple sliding animation, as does the carousel at the top with various images sliding across- However when I open the webpage at my place of work, the smooth slide animations are disabled (it literally just makes this appear and disappear, and the carousel just flicks between the images, rather than slides).
Could this be related to work corporation firewalls blocking certain bootstrap sources? Has anyone else ever had something like this, and hopefully solved?
Also - I know I could just do this via JS, but I just wanted to query this all the same as it's a very odd issue.

Is there a way to hide the Box-Model Graphic in Chrome Developer Tools?

I was wondering if anyone knew of a way to hide or remove the Box-Model Graphic at the top of the Computed tab above the Filters? It's the graphic that shows margin/border/padding and dimensions. It's not useful for me and I'd love to have the additional dozen lines of filters.
I spend about 4 hours every day in Chrome's Dev Tools and it's just one of those little frustrations it would be nice to fix.
Thanks!

UI Design/Development - Is there a feasible way of coding multidirectional gradients?

I've been browsing Dribbble this morning and found this nice UI design for a dating app, see screenshot below:
Now, this is an ever growing trend in design and it does look fantastic, but realistically is it possible to code an element that has a horizontal/diagonal gradient and fades out vertically?
If I were to do this I would probably do it using only CSS, which is fine for the colour gradient, but is there a way to also fade the element out vertically. The only other way I can imagine doing this is to generate the gradient as an image on the fly using server side code but I'd imagine that would use a lot of server resources to regenerate on the fly.
Info on other ways of doing it would be great, I've tried a couple of ideas but nothing has actually worked yet.

Creating a radial menu using very limited css and js

So I know that the question of how to make a radial menu has come up before and I am aware that some people have done absolutely amazing things already, but! I have to make one and I can't use anything more than css and js. The problem is, I have to implement the menu on the clients piece of crap drag and drop editor. It doesn't have anything fancy installed and isn't the most wonderful environment to work in.
To make matters worse, it has to be compatible back to IE8. I know. Trust me.
I was initially thinking of using a bunch of divs shaped as triangles layered over each other, but then I would have to cut off all of the tips poking out. Not sure how to do that.
Any ideas?
By the way, this is the triangle idea: http://imgur.com/YcWeOjE

Chrome and div background layers not loading properly

This is a very weird thing that i've experienced . I've been working on a project lately www.bandness.com, which allows music groups and bands to upload their music. The artistic department has been very keen and precise and they've done an incredible work that allows the bands to have gorgeous profiles .
However, when on Chrome (i've noticed this only happens in chrome), when you enter a profile the background image doesn't load properly until you scroll over it or you "select" the div layer or the ones on top of it.
here are some examples of what i'm talking about
you need to select the layer so it works properly, and that is bugging annoying!!
here you have another example
and this is how the website should be seen without the bug in the left screen
Why does this happen?
The website is www.bandness.com, click on any of the groups where it says "TOP 5 GROUPS" or on the group for each song in "TOP 5 SONGS" and you'll probably spot what I'm talking about.
This has happened to me in chrome, on a macbook pro with the latest OS release. As well as in Windows 8. It bugs me because I have NO idea what is causing this and I fear a chrome bug.
How could it be fixed? Any suggestions are appreciated, I thought of using jQuery to make the layer dissappear/appear or something like that... but i'm unsure of whether this will work.
Ok, so I'm posting this as a help for anyone that suffers the same consequences of this bug at any time.Bear in mind the answer implies using jQuery.
As Christopher kindly pointed out earlier, I tried to do $(SELECTOR).hide().show(), but that didn't make it.
Then I decided to try with $(SELECTOR).hide(100,function(){$(SELECTOR).show()}); ensuring that the effect of showing only happens once the div layer has dissapeared.(that way it actually appears and dissappears).
The solution worked, however this should not be needed and it doesn't provide an answer to why this is happening, but it "kinda" makes the trick .
$(SELECTOR).fadeOut(100,function(){ $(SELECTOR).fadeIn()}); makes this happen in a much fancier way. Again as I said this isn't a fix, it's just a workaround that might get you somewhere if you ever suffer this problem!
