The **Problems** panel in Android Studio is a centralized and shared issue panel
for all design tools, such as Compose Preview, Layout Editor, and Layout
Validation. To view the tool window, navigate to **View** \> **Tool Windows** \>
**Problems**.

**Figure 1.** You can view all the issues for your design tools in a shared

From the **Problems** toolbar, you can see the **View Options** , such as

Fix**.

**Figure 2.** The **Problems** panel has the following view options that you can
sort by either severity or name: Show Warning, Show Weak Warning, Show Server
Problem, Show Typo, Show Visual Lint.

Individual issue details are displayed in the **Issue Details** pane in the
**Editor Preview**. Each issue can be displayed in the built-in editor so that
you can preview the code.

## View issues with visual lint

Android Studio automatically checks for visual lint issues for your layouts that
are written in Views. When you open
[**Layout Validation**](https://developer.android.com/studio/debug/layout-inspector#layout-validation), you
can see all your layouts render in multiple device sizes. All visual issues,
including background visual linting, appear in the **Problems** panel.

Visual linting rules look not only at the current file, but also at the versions
of the same layout with different qualifiers--for example, `landscape` or
`sw600`, if they exist when performing the analysis.
