My Eclipse

Problem: same views in different perspectives MyEclipse 2022 Ubuntu Ubuntu 22.4
the problem occurs between perspectives: “Java Enterprise”, “Java” and “Debug”.
When I add or change the position of a view (eg “Problem”, “Console”, etc.), the change occurs on all perspectives.
with a new workspace the problem is solved.

Thank you for confirming that the issue does not exist in a new workspace.
You could try Window > New Window on your previous workspace and check how it works. This should clear the cache and reset all the perspectives.
