Windows 11 blur window bug
I rebooted my PC and opened Steam in a maximized window. After I closed it, the window was gone but I got this blur over my screen that overlaps everything. I'm using 2 monitors, the second one doesn't have this blur since the Steam window was on the first one.
I've seen someone here having the same problem. Is there a way to disable this blur effect until Microsoft fixes this bug?
P.S. Also, I've been having lags on file explorer when using the keyboard arrows to navigate, the only way to get rid of the lag is going fullscreen by pressing F11. Is there a working solution for windowed mode?
In the task bar, click "show desktop" then again to bring back up your windows. Fixed it for me without any shortcuts or system manuevers.
- That blurry screen issue sounds super annoying. Unfortunately, it's a known bug in Windows 11 where the acrylic blur effect from a maximized window doesn't clear properly when the window is closed. Here's a workaround until Microsoft rolls out a fix: you can try restarting the "Desktop Window Manager" process. Just hit up Task Manager, find the process named "dwm.exe," and restart it. This usually clears up any lingering visual effects.
- To temporarily disable the blur effect caused by the bug in Windows 11, you can try the following steps:
1. Right-click on the Windows Taskbar and select "Task Manager" from the context menu.
2. In the Task Manager, locate and right-click on the "Windows Explorer" process.
3. Select "Restart" from the context menu. This will refresh the Windows Explorer process and temporarily disable the blur effect.
4. Check if the blur effect has been removed. If not, you may need to repeat steps 2 and 3 or try other troubleshooting methods. - Make sure report this issue using the Feedback Hub app.

Windows 11 Pro 22H2, 22621.2861 OS Buildstill having this bug, been running into it for months. very annoying khyodo2285
Unfortunately this issue as of November 2023 is still on-going and cannot be fixed permanently. If you restart your display driver, it will temporarily solve the issue. Simply do:
CTRL+SHIFT+Winkey+V
This should restart your display driver and remove the blur caused by the snap assist feature.
I read all the suggestions here and couldn't find anything as simple and efficient as this temporary fix...It's CTRL+SHIFT+Winkey+B
- hi, I have a problem in two ways, I'm currently using Windows 11 Pro and on Windows Defender I have a problem with identity theft protection, it doesn't work for me when I'm off, but it should be on and in safe mode it says explorer.exe system warning unknown hard error, please fix the bug, thank you very much lp
Hi,
After looking through a bunch of answers that didn't work for me, I found that Win + X and then just clicking 'desktop' did the trick. An easy fix for something that was driving me absolutely nuts.
Cheers!
- Thanks for sharing this helpful answer. Worked great on my laptop.
- This worked for me, and i now i cannot get it back. You see, i actually wanted to see how i can apply this to more screens (as in to control it), but seems that it is a feature which is still under development.
- A year and a half later and the current insider build STILL has me experience this bug at least once a day. I have found no permanent fix.
- Yes, exactly this is still a bug that is happening randomly.
The only solution is to restart the PC.I'm getting this as well, it's becoming more frequent. Can't figure out the cause.
