I've been using Sublime for a couple of years now and it's been fine until a couple of days back, when I upgraded to Ubuntu 14.04 on a AMD APU A10 machine. I was using 12.04 on a Core i3 processor till then.

My Configuration is:
AMD APU 10 - AMD Radeon HD 8650G 2.5 GB Dual Graphics.
8 GB of Ram and 1TB HDD.

I use my laptop's display which is 1366x768 and a monitor which is 1920x1080. Everything worked fine with the old laptop, but in the new one, when I drag and select text the latency is incredibly high. The scrolling of a 500 line file is also very sluggish and I am not able to experience the smoothness I was used to with Sublime.

I have the proprietary Catalyst driver - fblrx v14.10 which seems to be the latest one.

I am having a major productivity loss. Can anyone help me out here?

Btw, I tried fgl_glxgears and the fps is ~ 800 on the laptop screen and 400 on the larger screen.

Try changing scrolling speed setting to -.

"scroll_speed": 0,

The AMD proprietary driver is good only for 3D rendering. When it comes to 2D, the overall performance is quite poor.

However, if you install the open source driver, it is the opposite: 2D is far better, 3D performance are a mess.
