Why does Microsoft Edge sometimes (randomly) partially minimizes itself?

Question

Why does Microsoft Edge sometimes (randomly) partially minimizes itself?

Michael Wexin 0

I still cannot figure out why does Microsoft Edge sometimes (randomly) partially minimizes itself. I usually run about 5-10 open Edge Windows in FULL-DISPLAY-SIZE mode, and within many of them, I may have anywhere from 2 – 10 tabs.

My system is this: Running Windows 11 Pro (16 GB) Desktop PC with two monitors in full 4K (3840 x 2160), using DisplayPort connectors with Nvidia 4070 Ti card with driver 595.79. My Display Scale is set to 150% (recommended). I have my “Power” setting set to the following: Turn Off monitor after 15 minutes, Make my Device Sleep = Never and Make My Device Hibernate = Never.

Please see the next three screenshots of what happens:

1 - This is when the Edge window is randomly minimized.

2 - This is when I try to click the “Max the Window” and as soon as I hover my mouse hover over it, I get these different “looks” pop up. I just ignore them and click on the Maximize and this happens:

Edge Small - 2.jpg

3 -I then click Maximize again, and the Edge is back to full, normal size as I always want it to be.

What going on there? I have read that some USB devices my trigger this, but I don’t plug in or take out any USB devices, and sometimes my system works perfectly for days at a time, and sometimes, these random Edge window minimizations happen 3 or 4 times per day. Also, sometimes these issues “fix themselves” on their own without any clicking on Edge Window size manipulation.

This situation has been going on for at least 6 months, so plenty of Windows’s updates and graphic driver updates have happened over the time. I have not changed any hardware in my PC for over a year and otherwise, my system works perfectly.

Any suggestions / feedback is much appreciated.

Try pressing F11 to exit the window from full-screen mode. You may have to select (click on) the title bar before pressing F11.

Hello Michael Wexin,

Welcome to Microsoft Q&A forum.

Before we proceed further, I'd like to ask a few questions to better understand the situation.

Do you have this issue in any other browsers or app? File Explorer count too.
Do you also encounter this when switch between Windows and games? Especially old games.
Does this also happen if you disconnect one of the monitor?

I'm waiting for your reply.

Thanks for your reply.

Here are my answers:

Do you have this issue in any other browsers or app? File Explorer count too.

NO, it only happens on Edge and I don't even have any other browsers installed.

Do you also encounter this when switch between Windows and games? Especially old games.

NO, I don't even have games running. Only Outlook and Edge.

Does this also happen if you disconnect one of the monitor?
I never tried that.

Hello Michael Wexin,

Thanks for replying.

This actually happens to me sometimes. But for most of the time it is because of the native resolution of old games and apps that no longer receive updates. Usually, it can be fixed by changing the resolutions of the affected apps, which depends on whether or not your GPU supports this function.

Additionally, can you please try to disconnect one monitor, it will help to see where the issue come from.

Hi. I don't have or play any games when this happens. It's a very strange behavior that appears and disappears days at a time.

I see that another user had an interesting idea. May I know if this get fixed after you use F11 to enter and exit full screen mode?

I'm waiting for your reply.

Hitting F11 doesn't help this. All it does is make my Edge window big, and when I hit F11 again its back to how its supposed to be . The problem is WHY does my Edge window shrink down by itself in the first place.

Hello Michael Wexin,

Thanks for replying.

For my case, it is because of the stretch of the resolution from old games. However, you don't play any games, and this appears randomly.

One more question remains, does this happens when yu have 1 monitor disconnected?

I'm waiting for your reply.
