Torch super slow with any custom watch face

Hello,

Since I've had the I3, I've found that any watch face that isn't a built in one causes the watch the be unusably slow.

With the torch, it takes 3-10 seconds to turn on, and then can't be adjusted as the adjust options just flicker on screen. Widgets take ages to load too.

It's common to all those I've tried, and very much takes some of the joy out of a customisable screen to have to stick with stock faces.

Can anyone tell me if this is an identified bug, please? 

Thanks

James
