Blurring miniatures in Xiaomi Redmi Note 8 Pro

Owners of the popular Xiaomi Redmi Note 8 Pro smartphone often encounter visual artifacts that can be confusing.One of the most common complaints is blurring thumbnails on desktop or in a gallery. Users notice that app icons, system widgets and photo previews lose their clarity, becoming blurry.

This is not always a sign of a major breakdown in the display, and most of the time it's caused by software settings on the MIUI shell or specific image processing functions, and understanding the nature of these artifacts will allow you to fix the problem yourself without going to a service center.

In this guide, we will go into all possible causes, from harmless personalization effects to more complex hardware problems, analyze the settings that affect graphics rendering, and offer step-by-step solutions to restore clarity to the interface.

Boque effect and software filters

The first thing to rule out is activating the Boque effect function in the personalization settings. Some of the design themes for the Redmi Note 8 Pro include background blur, which also affects interface elements, a software simulation of the optical effect characteristic of professional photography.

This feature is designed to focus on content, blurring the background, but on screens with a resolution of 1080×2340 pixels, poor implementation of the blur algorithm can lead to soap on the text and small details of icons.

Check out the active themes in the design menu. If you use a third-party design, try switching to the standard Classic or Default system style. Often custom themes contain scripts that force the desktop layer to be eroded.

⚠️ Note: Some themes from unofficial stores may contain malicious code that not only changes the visual style, but also consumes CPU resources, causing lags when rendering graphics.

To turn off the effect, you need to go to the theme settings. Find the Settings section → Wallpaper and personalization → Theme. Here you should reset the changes to factory. If the blur disappeared after that, then the problem was purely visual style.

Scaling and font settings

The next common reason for thumbnail distortion is the incorrect interface zooming settings. Users often change the size of the font or interface elements to improve readability without realizing that this affects the rendering of the entire graphics.

When you set up too large a font or maximize the magnification of elements, the system is forced to stretch vector and bitmap images, resulting in icons of applications that were originally designed for a certain size become blurred and lose clear contours.

This is especially evident in the list of recent apps and in weather widgets, and to check if this is the cause, follow the following steps:

• 📱 Open the Settings menu and go to the Screen section.
• 🔍 Find text and display size or similar in your version MIUI.
• ⚙️ Return the scaling sliders to the default position or Recommended.

Also worth noting is the feature of Enlarged Text in the special features section, if activated, the system forcibly changes the DPI (pixel density) for the entire interface, which often leads to artifacts on thumbnails.

💡

If you have a blur after resetting the scale, try restarting the device, which will clear the graphics buffer cache and cause the system to redraw all the elements again.

Problems with launcher and gallery cache

Android and MIUI are actively using caching to speed up work, but over time, errors or corrupted files can accumulate in the thumbnail storage, which leads to the system displaying a blurred square or incorrectly processed preview instead of a clear image of the icon.

The most common cache is the POCO Launcher or MIUI Launcher system launcher, and the Gallery app, which is a safe procedure to clear and does not delete your personal photos or contacts, but resets the settings for the location of icons on desktops.

To perform cleaning, follow the instructions:

1. Go to Settings → Applications → All applications.
2. Find the System Launcher (or Desktop) in the list.
3. Select Memory and click Clear.

The same procedure is recommended for the Gallery app and the Media Storage system service, which are responsible for generating preview photos, and if the thumbnail database is damaged, you will see blurred squares instead of photos even after you reboot.

Hardware Display Problems Redmi Note 8 Pro

Unfortunately, we can not exclude a physical malfunction of the matrix. IPS-If you don't see all the blurs in the screen, but you see a film or a fog in a certain area, it's a warning sign.

A common problem is the detachment of the display plume or degradation of the polarization layer, in which the image may appear blurry, as if water had been spilled on the screen, but the touch slope continues to work properly, which differs from software blur in that it is independent of the content displayed.

The hardware problem can be diagnosed using a test image:

• 🖼️ Open a full-screen black or white image.
• 👀 Carefully inspect the display from different angles in bright light.
• 💧 Look for spots, color changes, or areas where pixels glow dimmer.

⚠️ Warning: If you see rainbow spots or “leaked” paints that do not change when you switch pictures, most likely, the display module itself is damaged or the plume has oxidized.

Effects of protective glass and films

And the most common factor, which is poor protective coatings, is that cheap hydrogel films or matte glass can create diffuse light scattering effects, which is visually perceived as a general blurring of the image, especially when the screen is bright.

Matte coatings are often used by gamers for glare, but they sacrifice clarity. If you've recently changed your screen protection, try taking it down and evaluating the image quality on a holo display. The difference can be drastic.

Also check the screen clean. Fat spots from your fingers, especially if they're spread over the surface, create an optical lens that blurs out fine details. Use microfiber and a special optics cleaner.

Resetting and system update

If software methods don’t work, the radical but effective way is to completely reset the settings. In the Redmi Note 8 Pro, this often solves problems with graphic artifacts caused by deep errors in system configuration files.

Before starting the procedure, make sure to back up the data. The reset will delete all user data, applications and settings, returning the phone to the “out of the box” state, which is guaranteed to eliminate the software conflict of the display drivers.

Pathway to reset: Settings → Phone → Settings Reset → Erase all data. Once turned on, the phone will undergo initial setup. If at this point, at clean, blur is maintained, the probability of hardware failure is 100%.

💡

Keeping blur after a complete reset and setting a standard theme is a direct indicator of a physical malfunction of the display module.
