The border around is blue - the default for every form. See at the properties. There is no possibility to set the border of the rectangle to another color. There is also no possibility to set the form without any border. Two possibilities to solve this problem: 1. Set the default of the forms to a form without any border. 2. Add a dialog to change the color of the border. Tested this with OpenSUSE 15.2 and LO 7.0.4.2. The same behavior is in all tested older versions of LO.
Confirmed also with Version: 7.0.3.1 Build ID: d7547858d014d4cf69878db179d326fc3483e082 CPU threads: 8; OS: Mac OS X 10.16; UI render: default; VCL: osx Locale: fr-FR (fr_FR.UTF-8); Langue IHM : fr-FR Calc: threaded
The Bug still exists in 7.3.7.2.
