The instant preview mode is more or less on par with 4.2.7.1 (I'd say it's still choppier). When instant preview mode is off the zoom is still not as smooth as it was in 4.2.7.1 and it still freezes for several seconds if I zoom above 25% (usually at about ~12-10%), it's way better then it was but when I compare both versions the 4.2.7.1 is a really smooth ride without any hiccups while the current fix is still a bit choppy and freezes. To be precise the freeze doesn't happen if you zoom out very slowly and I mean glacial slow, my hand barely moves, then it doesn't freeze but it takes me half a minute to zoom out at this speed. I'm sorry, considering this was resolved with the fix, to suggest there might be something more to open it again? -- You are receiving this mail because: You are watching all bug changes.
