Hi @fgprata,
Could you share your workflow or show us the activities you are using and their configuration?

The problem occurs before opening the project, in settings for example … Every time a tooltip is fired.

Every icon i pass the mouse over…


Try to open Studio as Administrator. If effect is still the same then probably your studio isn’t updated correctly. You need to do clean install based on this post:

I already do that, looks like its .net problem.

Try to install the newest 4.8 .Net Framework.
