Look at the blue box in the first page: rounded in Power Point, not rounded in Writer

(In reply to m.a.riosv from comment #3)

No, this is about rounded corners, while bug 49247 is about blurry effect on edges.
Comment 5 NISZ LibreOffice Team 2020-12-01 13:44:12 UTC
This is a VML shape v:roundrect with text inside it. Converting to DML in Word makes the rounded shape import correctly.
Comment 6 Aron Budea 2021-02-14 18:10:31 UTC
The borders are rounded after the following commit, but the shape is now smaller than the text box, which is a regression.

Rendering it LO 7.1.1

This is what the original sample file looks like in LO Writer 7.1.1. Probably what Aron mentions.

Not only is the border too small for the content, but also the rounding seems to have a radius too small.

The problem still exists in Version: (X86_64) / LibreOffice Community
Build ID: 56f7684011345957bbf33a7ee678afaf4d2ba333
CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: CL threaded

The shape is imported as legacy rounded rectangle according to v:roundrect element in the file. But the file has in addition a v:textbox element. Such shape should be imported as drawing object 'text box'. Otherwise the attribute "mso-fit-shape-to-text:t" cannot be translated. The drawing object 'text box' has rounded corners too, so that is not a problem.

The radius of the rounding is half as large as it should be.

It seems the description in https://learn.microsoft.com/en-us/windows/win32/vml/msdn-online-vml-arcsize-attribute:

"Defines the rounded corners of a rounded rectangle as a percentage of half the smaller dimension of the length and width of a rectangle. 0% would have square corners, and 100% would form circular corners. A square with an ArcSize value of 1.0 would be a circle. The default value is 0.2 (20%)."

does not fit to the reality. When the handle in the shape is dragged to its maximum, creating a circular rounding, then MS Office writes arcsize="0.5". So in reality the reference value is not "half the smaller dimension" but the "smaller of height and width".
