Description: Zoom of a complex 3D shape very slow (Skia Raster and previously GDI) Steps to Reproduce: 1. Open the attached file 2. Zoom in out (lag) (not rendering each and every zoom frame with CTRL+Scroll wheel would probably improve thinks) 3. Zoom in to 280% and scroll up/down left right (lag) Actual Results: Lagging Expected Results: Little more speed would be nice Reproducible: Always User Profile Reset: No Additional Info: Found in 7.4 and in Version: 7.2.1.0.0+ (x64) / LibreOffice Community Build ID: 8fdbb8aed1b48734a717d5f98ada566de7204605 CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win Locale: nl-NL (nl_NL); UI: en-US Calc: CL and in 7.0 and in 4.4.7.2

Nothing to do with Skia, time spent somewhere in drawinglayer.

Zoom in out (lag) (not rendering each and every zoom frame with > CTRL+Scroll wheel would probably improve thinks) The rendering speed/buffering for smooth zoom & pan aside, lets not screw with the zoom step behavior for the sd canvas. We already have residual of bug 45705 to bring keyboard zoom in/out (via UNO) in line with the Zoom bar and <Ctrl>+MouseWheel controls for Draw & Impress--to match consistent behavior of Writer, Calc and Math. The zoom steps need to be consistent for all zoom modes, by mouse, zoombar, and keyboard. And, no performance improvement to be found there!
The problem is, that the object has about 12000 cylinders.

We need retesting with attachment from comment 5.
