Steps to reproduce:

1. Run the capex. The green square should appear brown with the Tint effect applied correctly.

2. Works fine on Firefox v21

3. Doesn't work on Chrome v27 or IE 10

I'm pretty sure this was working one or two versions ago

Observed result:

Green square

Expected result:

Brown square

Browsers affected:

Chrome: yes

Firefox: no

Internet Explorer: yes

Operating system & service pack:

Win 7

Construct 2 version:

137

Ah forget about this it's working fine now.

Not sure why I was getting inconsistent results.

Shaders require WebGL support, which IE10 doesn't have and Chrome and Firefox will disable if your graphics card drivers are out of date.
