There's definitely a redrawing issue of some kind. I can see a similar issue already in Version: 7.1.5.2 / LibreOffice Community Build ID: 85f04e9f809797b8199d13c421bd8a2b025d52b5 CPU threads: 8; OS: Mac OS X 10.16; UI render: default; VCL: osx Locale: fr-FR (fr_FR.UTF-8); UI: fr-FR Calc: threaded In my case, a first form with a green background. Switching to second form in list of forms shows a form with a blue background, and an overlapping green border from the first form. Some of the controls from the first form are displayed in the preview of the second form. Confirming.
As a member of QA, I've already commented, or is someone else supposed to take up on that QA:needscomment ?
Created attachment 175233 [details] example of an empty BASE file the trick is, that both forms have to have different backgrounds and the screen size of each form must be different between the two forms *not maximised windows of the forms
