%%%Using Ubuntu 64bit r43554

I attached a sample blend and picture of the problem. If you look at the camera preview of a simple cube+plane scene in cycles, the plane seems to extend in the Z like it is following some sort of imaginary perspective lines that eventually converge into a single point.

It only seems to happen in the camera view though.%%%

%%%I also had another side bug, but I didn't feel it warranted its own report:

If you remove the world settings for this scene, I noticed that wheeling in/out in the camera preview, triggers cycles to rerender, but still seems to have the old world settings in effect until I do a change like tab into and out of edit mode on the cube to cause an update. ie: the purplish background stays in place and only goes to black if I enter/leave edit mode on the cube, even though the world settings were deleted.

Anyways, seems minor and probably expected cause of all the depsgraph stuff, but thought you might want to know. Later o/%%%

%%%First issue isn't actually a bug. You just zoomed out too much. "Artifacts" like this plane are quite common when zooming out perspective camera too much. It's just how perspective works :)

Second issue indeed seems like missed update trigger or so. Brecht, can you please check removing world settings?%%%

%%%I just happened to be zoomed out alot in that picture to see the extent, but even with it is zoomed in via "home" to fit the window, you can still see it extend down. But if you say this is expected, then I will take your word for it :) I just thought it was a bug since it only happened in camera view (well, perspective).%%%

%%%I can't confirm the missing world update with SVN 43527. If I remove the sky texture or the complete background, the viewport updates to the correct result immediately. %%%

%%%Ahh, I just looked at the scene in wireframe mode while in camera view, and I see why the perspective is to blame now. I guess it just wasn't so obvious when looking at it in cycles, my apologies! (guess I had the bugs priorities backwards hehe)

As for Thomas's reply, I get correct/expected results if I just delete the sky texture node, but the problem I have is when I unlink the datablock for the world settings.

ie: Go to world panel and click the "X" beside the "World" texture. Wheel zooming still refreshes cycles, but it keeps the background.%%%

%%%As a bit of a catch up from irc, it was pointed out by Thomas that tabbing into edit mode while cycles is rendering, after you had unlinked the world datablock, it would crash.

At first I didn't get the crash, having just downgraded back to r43527, but I do get the crash after having svn up'd back to r43569. I will attach the backtrace to this report%%%
