Probably I am doing something wrong and hopefully a simple fix - I am seeing the up triangle sprite overlaid on all sprite images when using a custom theme. As seen here.
I had gone through the process of creating a custom theme based off of material through here. In the generated kendo.custom.css file, I replaced all references to images (url('none/sprite.png'); with the proper path on my web server.
Everything looks fine with standard material theme:
<link href=
"https://kendo.cdn.telerik.com/2017.3.913/styles/kendo.common-material.min.css"
rel=
"stylesheet"
type=
"text/css"
/>
<link href=
"https://kendo.cdn.telerik.com/2017.3.913/styles/kendo.material.min.css"
rel=
"stylesheet"
type=
"text/css"
/>
But the sprites become overlaid after I specify my custom theme:
<
link
href
=
"https://kendo.cdn.telerik.com/2017.3.913/styles/kendo.common-material.min.css"
rel
=
"stylesheet"
type
=
"text/css"
/>
<
link
href
=
"../../Content/kendo.custom.css"
rel
=
"stylesheet"
type
=
"text/css"
/>
