I displayed the Edit Points toolbar by going to View>Toolbars>Edit Points. After selecting a curve and going into points editing mode, I clicked off the curve and the Edit Points toolbar disappeared. While it is normal for the toolbar to appear and disappear with the selection and deselection of a curve when in points editing mode, I did not expect the toolbar to disappear after opening it by going to View>Toolbars>Edit Points.
Reproduced with a recent master build: Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 61b41646c5a93ca24f2c9f143cdb0da2c9258989 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded If the toolbar is turned on via the menu, it remains visible until edit point mode is entered with Edit > Points (or F8), a shape is selected and then deselected. It then disappears. I'd expect the toolbar to remain visible if I decided to show it by turning it on in the menu (even if everything is greyed out). At least so the other toolbars don't jump to a different position every time edit point mode is entered. Already the case in OOo 3.3, so inherited.
This particular case is probably a special case of bug 38850, bug 106846 or bug 107495. Maybe should be marked as a DUP of one of these?
You're right, bug 107495 is a good match. Thanks Seth! *** This bug has been marked as a duplicate of bug 107495 ***
