I have problems with chromium ever since I have this laptop. I'm developing a web application, which uses a lot of javascript to change CSS dynamically. For example you click a button and a dialog appears. The problem is that not always after clicking display is updated. It's like CSS is updated (I can see it in dev tools), but the screen stays the same (after moving mouse over the element in html inspector, it magically shows up on screen. I have discovered that "Accelerated 2d canvas is unstable in Linux at the moment", so I disabled it. I think this has solved this problem. Now I have different problem, sometimes cpu usage goes very high, it usually happens when browsing facebook. Sometimes killing chromium --type=gpu-process helps. I don't know if it's caused by disabling accelarated 2d canva. Also now I have problems with text cursor, it refreshes with very low frequency.
I have radeon HD 7870m, but I disabled it for better battery life. The problem of canvas not being updated happened anyway with the open source driver and the temperatures were really high so I prefer to have this radeon powered down. On my old PC I had radeon hd 4850 with properiaty driver and all worked ok, accelarated 2d cnvas was disabled by default, but there were no spikes of cpu usage now and then.
Has anyone had similar problems?

I also have this issue. I think accelerated_2d_canvas is disabled by default. https://code.google.com/p/chromium/issu … ?id=518209 might be helpful.
