Is there any sort of overlay software that's running as a part of your graphics card/? Those boxes don't look like anything the Terminal would ever draw on its own... This vaguely reminds me of those NVidia ShadowPlay threads - but obviously not the case here. Maybe something like: |

I've tested with all possible combinations of those two options and the issue still remains. I think it may only happen with more than one tab if that helps. |
For what it's worth, those experimental rendering settings don't hot-reload (from what I remember). You'd need to open a new tab.
That's weird for sure. Does that box stay aligned with the top left of the Terminal window, as you move the Terminal window around/? You might be able to use WinSpy to figure out what that box is, if it's an actual HWND. Use the little finder tool to drag over that box. I'll be stumped if that doesn't find some sort of HWND there (other than the Terminal) |
@zadjii-msft those look like pseudowindows...! In the old days, when you minimized something it actually became Iconic. Like, the window itself changed to rendering just an icon and a name. After the old days, windows became very tiny. In Windows 95, if you killed Explorer you would see stacks of minimized windows, 60x16 pixels wide, accumulated at the bottom of the screen. This looks like what might happen if you make a pseudoconsole window visible and minimize it.... |
@asineth0 are you using any third party window management software? |
I did a bit of testing and can confirm it goes away with software rendering. Had to completely close out Terminal and reopen it for it to be fixed. In terms of window management software, the only one I have installed is PowerToys (not sure if that counts). |
Wow, I'm baffled. All of the regions you pointed out are outside the part of Terminal to which software rendering even applies. Thanks for testing! |
That kinda backs up my theory that this is a graphics card issue. Switching to software rendering got the GPU and any other software out of the way, and the problem went away? Not sure how we wanna go about this one. We don't' have the hardware to repro and ID the root cause ourselves, and you've got a viable workaround - you okay if we close this out? |
Yeah, that's fine. |
Hi! We've identified this issue as a duplicate of another one that already exists on this Issue Tracker. This specific instance is being closed in favor of tracking the concern over on the referenced thread. Thanks for your report! |
This is still an issue as of 05/14/24 on the latest version. Often happens with any terminal I leave open maximized, doesn't happen with windows that are just floating. |
Windows Terminal version
1.14.1963.0
Windows build number
10.0.22000.795
Other Software
GPU: AMD Radeon 5700 XT
GPU Driver: 31.0.12015.2001 (7/13/2022)
I can confirm this happens with no other apps open.
Steps to reproduce
Open Microsoft Terminal, and wait a few minutes. Minimizing and unminimizing the window makes a different set of squares appear in the bottom left of the screen.
Expected Behavior
No squares should be randomly rendered to the screen.
Actual Behavior
The square that appears in the top-left of the window:
The squares that appear in the bottom left of my screen when the window is minimized:
