There's a discrepancy between the screenshot in comment #1 and that in comment #3. The screenshot in comment #1 shows extensions clearly running, and the screenshot in comment #3 suggests there are none.
After you have disabled all extensions, please:
1. Log out and in again.
2. Tell us if the bug still happens.
3. Provide a new screenshot of the whole desktop.
4. Run this command:
gsettings list-recursively org.gnome.shell > settings.txt
and attach the resulting text file here.
