Are the descriptions not visible for you?  If so, the following should
help:

"Screenshot from 2021-09-06 20-27-24" depicts the relief drawn on
MS-Windows.  (Which does not exhibit the bug)

"Screenshot from 2021-09-06 20-28-53" depicts the relief drawn on
X-windows.

"Screenshot from 2021-09-06 20-30-11" depicts the bug on X-windows.

Thanks.
