Slint window becomes transparent in fullscreen when using layouts with Text

[JanP1]

Has anyone experienced a problem in Slint where a window set to full-screen: true becomes transparent after switching virtual desktops on Windows or using Alt+Tab, only when the window contains at least one Text element. The app itself does not crash, and the issue does not occur if the Text is removed or if the window contains only simple Rectangle backgrounds.

I haven't heard of this issue yet.
I'm assuming your using femtovg as a renderer? (the default)

I was using the default renderer. After setting SLINT_BACKEND=winit-software, the problem seems to have disappeared.

To add more detail:

• the issue doesn't happen when the window is bigger than the screen resolution and centered (covering the whole screen)
• the issue happens when it isn't set to 'full-screen=true' , but it is the same as the screen resolution and centered
