STM32CubeIDE "Device configuration tool" hides all views from "C/C++" perspective

[sintech]

Sometimes (not always) when I click .ioc file to open "Device configuration tool" it starts ok in its own perspective but when I click button to generate code and return to my C source file, I notice that all "C/C++" perspective views like "Console", "Problems" etc are hidden.

Even if I click Window->Show View->Console nothing changes.

Sometimes it happens when I close "Device configuration tool" without saving.

I found two options to return them back: File->Restart or reset "C/C++" to saved state which also resets all customisation (windows size etc.).

I observe this bug at least from 1.5.x version of cubeide.
