--- Comment #7 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Confirmed. On Windows 10 Home 64-bit en-US with
Version: 6.3.2.2 (x64)
Build ID: 98b30e735bda24bc04ab42594c85f7fd8be07b9c
CPU threads: 4; OS: Windows 10.0; UI render: GL; VCL: win; 
Locale: en-US (en_US); UI-Language: en-US
Calc: threaded

and recent masters.

These are thumbnails from the Windows Explorer (shlxthdlr) built-in extension
[1][2], not thumbnails used on the StartCenter and Template manager backing
window.

Don't know if the GDI plus bitmap extraction can generate a PNG with alpha
channel transparency. But if it can, this integration with os/DE shell would be
cleaner--especially as Windows has now implemented its Dark 'default App mode'
theme.
