I got the same issue.
As @asturur suggested, I create an issue in chromium bug tracker: https://bugs.chromium.org/p/chromium/issues/detail?id=602933

We need a sample code that fails.
I can apply shadow to object, rotate as much as i want and everything is fine.
Please attach the code or close the issue.

here is a jsfiddle showing the issue :

the object is shadow applied but not showing because it rotated, and here is without rotation :

working for me.
try to disable hardware acceleration from your browser and check if it makes any difference.

asturur on 28 Mar 2016

it dosn't make any difference. still not working here is a gif showing it :

Can you share some detail on your os version, videocard and browser using. I got no problem with firefox or chrome. Did not try ie11 to be honest.

asturur on 28 Mar 2016

it win 7 64bit, chrome : 49.0.2623.87 (latest) , opera : 36.0.2130.32 (latest), videocard: Radeon HD 7690 XT

the issue is present just in those browsers, firefox and IE7 is working perfect.
Thanks.

I will try to get same chrome version tonight. Not planning to install opera. They are on blink rightnow, not webkit anymore. I think safari is the only one on standard webkit.
Are you sure you disabled hw acceleration and restartrd browser? It does not look like sonething that we can fix.

asturur on 28 Mar 2016

i disabled hw acceleration and restartrd browser, and the issue is still there, i tested on other computers and it the same problem for those browsers.

keanass on 28 Mar 2016

any updates about the issue ?

keanass on 29 Mar 2016

it is a browser bug i presume. Problem with chrome.

asturur on 29 Mar 2016

so no solution for the moment !?

Solution will not come from us, because 2 weeks ago everything was fine on
chrome and still is on chromium.

You should have been writing on chrome issue report since start.
Of course you have to make a plain canvas example with no fabricjs and they
are strict about issue opening.

But this is how it should be.
