Several IDLE GUI tests fail on newer Tk or are fragile under display scaling. All test-only.
test_sidebartest_mousewheel fails on Tk 8.7+, which replaced the X11 <Button-4>/<Button-5> wheel events with <MouseWheel>.
test_configdialog compares ttk widget states with exact tuples, which break when a widget picks up transient active/hover states from the pointer (whose position shifts with the scaling). The tested methods only toggle disabled, so the tests should assert that flag alone.
Several test_configdialog tests re-mask a method at the end, which is skipped on a mid-test failure; addCleanup() makes it unconditional.
