Hello once again.
Update on the black screen problem.
Turns out, the black data panel screen occurs when adcefwebbrowser.exe is set to 'High performance' GPU setting (see picture). In my case this is in Catalyst Control Center. Other general settings don't seem to matter, unless it has been told to use 'based on power plan' setting, which probably takes the info from the power plan settings, and if those are set to 'max performance' it will run into troubles. Otherwise, if power plan is set to 'max performance', yet adcefwebbrowser.exe is in 'Power saver' profile, it will work fine.
So the problem happens in any instance when the above mentioned .exe is launched in max performance profile.
Side note. In graphics diagnostics, it never shows that Fusion360 is using advanced graphics. Only integrated one. Even when Fusion360.exe is opened with high performance profile and max power plan. No idea if it is actually using it or not.
