Are the small dots appearing in the Windows 10 Task Manager sidebar a bug or a settings issue?

When I open Task Manager, I notice some mysterious small dots in the sidebar. I’m not sure if this is a system display bug, a visual indicator for an enabled feature, or a setting that needs to be ad...

It is completely understandable why those dots feel like a glitch. Usually, when we see unexpected artifacts on a screen, our first thought is "GPU driver error" or "corrupt file". However, in this specific case, it’s actually a design feature rather than a bug or a hardware failure.

Those small dots (often appearing as three vertical dots or a "hamburger" style icon) are part of the Navigation Pane toggle. They appear when the Task Manager window is resized to be narrow.

  • The Indicator: When the sidebar is collapsed to show only icons (without text labels), Windows uses those dots as a handle or a visual cue that the menu can be expanded.

  • The Bug Illusion: Sometimes, due to specific display scaling (DPI) settings or window snapping, the sidebar ends up in a middle ground where the dots appear slightly off-center or clipped, making them look like dead pixels or a rendering error.

Since this is a UI behavior, you can usually resolve it by adjusting the window layout:

  • Expand the Sidebar: Hover your mouse over the right edge of the sidebar (where the icons meet the data) until your cursor turns into a double-headed arrow. Click and drag to the right to reveal the full text labels (Processes, Performance, etc.).

  • Toggle the Menu: Click the three horizontal lines at the top left of the Task Manager window. This will force the sidebar to expand or collapse cleanly.

  • Check Display Scaling: If the dots look blurry or misplaced, right-click your desktop > Display settings > Scale and layout. Ensure you are using the "Recommended" percentage. Sometimes non-standard scaling causes the Task Manager's thin lines and dots to render poorly.

While it is "by design," many users consider it a UI bug in spirit because the dots don't always scale well on high-resolution monitors, leading to the mysterious look you described. If you expand the window or the sidebar, they should integrate back into the standard menu structure.
