Problem Description

Using spyder on a Windows 10 laptop connected to a bigger monitor with an HDMI connection. When I disconnect it, there is message window that appears with the message: “A monitor scale changed was detected. We recommend restarting spyder…” The issue is that this window appears behind the main spyder window and so cannot be dismissed as it is a blocking window. To dismiss it, you need to reconnect the monitor. Second, the window suggests to “Enable auto high DPI Scaling” which I did but the behavior remains the same.

What steps reproduce the problem?

1. Open spyder with a laptop connect with HDMI to a monitor
2. Disconnect the laptop from the monitor
3. The spyder window is moved to the latpop’s screen but it is blocked as there’s an erro message window behind the main window that cannot be dismissed

What is the expected output? What do you see instead?

1- The error message should be in front of the main window 2- if we tick the preferences / General / Interface / Auto high DPI scaling, the error window should not even open

@dalthviz I’m using spyder 5.3.0. Concerning the resolution, unfortunately I can’t say at the moment (it was not my screen and it might take some time till I get back there)

Thank you for the feedback @raphaelquast ! That makes things even worse 😨 (although not totally sure why the dialog layout would mess up in that way) What Spyder version are you using? Also could you share the resolutions you were using when this happened? Thanks!
