Operating system: Ubuntu 19.04
(All other operating systems are affected as well)
Broken: 2.81, 892c3891ed0b (2019-10-24 19:00)
Short description of error
When opening a Context Menu and accessing a submenu, it's possible to position the mouse cursor outside of the menu while keeping the parent entry in the context menu highlighted. Right-clicking with the mouse cursor in that position will make Blender ignore all further mouse input until the mouse cursor moves over other entries in the Context Menu. If the Context Menu only contains a single item, for instance in the empty areas of properties panel, then all mouse input is ignored until a shortcut is pressed.
Exact steps for others to reproduce the error
- Move cursor to a blank space in the Properties panel.
- Right click to open the Context Menu.
- Move the mouse cursor slightly below the Context Menu so that the Area menu entry is still being highlighted but the mouse cursor is not on the Context Menu anymore.
- Right click again.
