I have the same problem

[hugoattal]

A similar issue that I have which is probably linked, I find it difficult to move my Tauri app window between screens of different scale.

• By "moving", I mean dragging with the mouse
• By "difficult", I mean that the window keeps getting resized, and I can't make it cross the screen : the window is kind of stuck on the first screen

Here is my setup:

 ----------     ----------     ----------
| Screen 2 |   | Screen 1 |   | Screen 3 |
 ----------     ----------     ----------

• Screen 1 is 2560 x 1440 @ 125%
• Screen 2 and 3 are 1920 x 1080 @ 100%

I found that it's pretty difficult to move my Tauri app windows between Screen 1 and Screen 2, but it's okay between Screen 1 and Screen 3.

Temporal solution I found: move the window slowly between the screens, so it gets resized (due to the change of scale) before the cursor cross the screen.

Note: I'm on Windows 11 using Tauri 2

I have the exact same issue as @hugoattal. The window moves back while resizing and it's difficult to even get it over to the second monitor. This worked better in Tauri v1. Not perfect but much better than in v2.
