some applications have blurry elements after the elements are not used for some time and they unblur when i put my cursor on it

Not sure if you were ever able to resolve this somewhere else, but I've also had a similar problem for the longest (~years), and poked at it every now and then without really getting much of anywhere and put it off again and again. I decided to poke at it a little more after reading this, and a few other things, and the it seems like it may be at least partially related to driver-side anti-aliasing. I stumbled on FXAA in my Nvidia Control Panel global 3D settings (I've had a 980 Ti for the longest), and after re-reading its tooltips for like the 50th time I disabled it (I usually flip it on along with adjusting a few other things when I clean install fresh drivers), and it seems to have dramatically reduced text blurring (I tested with my Outlook Calendar, which pretty quickly shows this blurring effect). I'm pretty sure there's still a bit of blurring going on, could be related to/resolvable by cleartext or whatever, but it's a ton less than before. I turned off MFAA afterward for good measure, too. Seems to have also eliminated video playback flickering (I've been getting it in Prime Video lately, but it's appeared elsewhere before, and I frustratedly ended up trying to workaround to other players, or just dealing with it by avoiding whichever window/screen with my mouse cursor while watching lol).

TLDR; Disable FXAA in your graphics card's global 3D settings. For Nvidia: Open Nvidia Control Panel -> Manage 3D settings -> Anti-aliasing FXAA - Off. Not sure if AMD has this issue, or how to get to it, but I doubt it's that different.

I'll have to see if it works out over the next couple of days, but it looks good so far.

Hi

Thanks for your reply.

Given that disabling hardware acceleration didn't resolve the issue and you're also experiencing problems with video playback on DuckDuckGo, along with blurriness in Microsoft Teams and other applications, it seems the problem might be more deeply rooted in your system's graphics settings, drivers, or a specific Windows 11 feature that's not interacting well with your applications.

Here are a few additional steps to troubleshoot and potentially resolve the issue:

1. Update Display Drivers

Outdated or corrupted display drivers can cause a variety of display issues, including blurriness and flickering.

• Via Device Manager: Right-click the Start button, select Device Manager, expand Display adapters, right-click your graphics card, and select Update driver. Choose "Search automatically for drivers" and follow the prompts.
• Manufacturer's Website: Visit the website of your GPU manufacturer (e.g., NVIDIA, AMD, Intel) and download the latest driver for your specific model.

2. Adjust Display Scaling Settings

Sometimes, display scaling settings in Windows can cause blurriness in applications.

• Go to Settings > System > Display.
• Under Scale and layout, try different settings for "Change the size of text, apps, and other items." Sometimes, setting this to 100% can help, though it might make items on your screen smaller.

3. Disable Fullscreen Optimizations

For the specific apps experiencing issues, disabling fullscreen optimizations might help:

• Right-click the application's executable file or shortcut and choose Properties.
• Go to the Compatibility tab.
• Check the box for "Disable fullscreen optimizations."
• Click Apply and OK.

4. Adjust High DPI Settings for Problematic Apps

Adjusting High DPI settings for each app can sometimes resolve rendering issues:

• Right-click the application's executable or shortcut and select Properties.
• Go to the Compatibility tab and click on "Change high DPI settings."
• Check the box for "Override high DPI scaling behavior." Choose "Application" from the dropdown.
• Click OK and Apply.

5. Consider a Clean Boot

Performing a clean boot can help identify if background applications are causing conflicts.

• Press Windows key + R, type msconfig, and press Enter.
• In the System Configuration window, on the General tab, select Selective startup.
• Uncheck Load startup items.
• Go to the Services tab, check Hide all Microsoft services, and then click Disable all.
• Click OK and Restart your computer.
• Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.    These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.

6. Check Browser Extensions

Since you mentioned issues with DuckDuckGo, if you're using it as a browser extension, try disabling extensions to see if one might be causing the issue.

7. Use Built-in Windows Troubleshooters

Windows 11 includes various troubleshooters that can automatically fix some common problems.

• Go to Settings > System > Troubleshoot > Other troubleshooters.
• Run the Video Playback and Program Compatibility troubleshooter.

i did disable it but the issue is still there (i also restarted the pc). and i noticed Microsoft teams (new) has the same issue. i also noticed that games don't lag so i think i disabled it wrong. also i realized that when i watched YT videos on duckduckgo and pointed my cursor on the video box the video started flickering and getting blocked with black bar covering the video except the bottom part with the red bar and stuff

Hi

Welcome to Microsoft community.

The issue you're experiencing with blurry elements in applications, which resolves when you hover over them, might be related to hardware acceleration settings in Windows 11 and possibly in your web browser, such as Microsoft Edge, if you're using web-based applications like Outlook (New) or the DuckDuckGo app. Here's how you can disable hardware acceleration in both Windows 11 and Edge to see if it resolves the issue:

Disable Hardware Acceleration in Windows 11:

1. Right-click on the desktop and select Display settings.
2. Scroll down and click on Graphics settings.
3. Under the “Default settings” section, turn off the toggle for Hardware-accelerated GPU scheduling.
4. Restart your computer for the changes to take effect.

Disable Hardware Acceleration in Microsoft Edge:

1. Open Microsoft Edge.
2. Click on the three dots (…) in the upper-right corner to open the menu, and then select Settings.
3. In the Settings menu, select System and performance on the left sidebar.
4. Find the Use hardware acceleration when available option and turn the toggle off.
5. You will be prompted to Restart Edge for the changes to take effect. Click the Restart button.

Disabling hardware acceleration can help resolve issues with graphical elements in applications, as it switches the processing load from your GPU back to your CPU. This change can sometimes improve the rendering of visual elements in applications that don't handle GPU acceleration well.

However, be aware that disabling hardware acceleration might affect the performance of certain tasks that are optimized for GPU processing, such as video playback or graphics-intensive applications. If you notice a significant performance drop after disabling hardware acceleration, you may want to re-enable it for specific applications or adjust other graphical settings to find a balance that works best for you.

If the issue persists even after disabling hardware acceleration, it could be related to other factors such as display drivers, system scaling settings, or the specific applications themselves. In such cases, updating your display drivers, checking for application updates, or adjusting your display scaling settings in Windows might help resolve the issue.

Please feel free to let me know how it goes.
