--- Comment #11 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Using Telesto's test file, I can not confirm an issue with Skia Vulkan
rendering on Windows 10 Ent 64-bit. Zoom steps are crisp (Zoom bar clicks or
<Ctrl>+<mouseWheel>.  Likewise when zoom with GDI rendering, with or without
Hardware Acceleration, no delays and zoom steps are snappy all the way to
3000%.

Version: 7.0.0.0.beta2 (x64)
Build ID: 1c213561a365b5666167321de68c9977500c9612
CPU threads: 8; OS: Windows 10.0 Build 18363; UI render: Skia/Vulkan; VCL: win
Locale: en-US (en_US); UI: en-US
Calc: CL

Skia configuration...

RenderMethod: vulkan
Vendor: 0x10de
Device: 0xffe
API: 1.1.119
Driver: 442.296.0
DeviceType: discrete
DeviceName: Quadro K2000
Blacklisted: no

However for this os/DE driver & GPU hardware, there is an issue when I place
Skia rendering in raster mode. The Zoom function (<Ctrl>+<scrollWheel>; or
'Zoom in' button on zoom bar) takes progressively longer to complete each step.
There is a noticible lag with Skia raster mode rendering. Can get well ahead of
the rendering (i.e. until the Zoom factor reaches its 3000% max in Draw).

Get this Stack Trace while the zoom step processes...
