Stop automatic window resizing


My problem is that i have an object that is supposed to fill the whole screen, but when it gets close to the edge of the display the window gets resized. If I apply the “fix” it creates some other weird changes(see screenshots). I hope I haven’t missed anything crucial or somethign stupid I have done, if so im very sorry. I would be grateful for any help.

What MCU/Processor/Board and compiler are you using?

For development purposes im just using the simulator.

What LVGL version are you using?

I’m currently using LVGL version 7.3.1

What do you want to achieve?

I would just like to know what causes this issue and how I could make an actual fix.

What have you tried so far?

I’ve tried all I could think of, and looked into the different lv_… c files without any luck.
I have noticed that there is already one post regarding this issue but I couldn’t get the suggestions to work.
If i use:

lv_page_set_scrollable_fit(lv_win_get_content(my_window), LV_FIT_NONE);

I get a weird layout change(see screenshots)

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

I have included what I think is all the relevant code.

Note that this is including the “fix”:

lv_page_set_scrollable_fit(lv_win_get_content(my_window), LV_FIT_NONE);

And i have kept styles and other stuff even though I dont think its the “culprit”.
I’m sorry if i have missed something.

Before adding:

lv_page_set_scrollable_fit(lv_win_get_content(my_window), LV_FIT_NONE);

And with the annoying resizing

After adding:

lv_page_set_scrollable_fit(lv_win_get_content(my_window), LV_FIT_NONE);

And apperently without the annoying resizing, but this weird cut of the logo at the bottom, and other layout changes

Has anyone got a solution? Because im very confused as to why its cutting of the bottom of my screen

Okay, I have been playing around with this and realised that im just a bit of moron.
It was the placement of the line:

lv_page_set_scrollable_fit(lv_win_get_content(winWifi), LV_FIT_NONE);

that was the problem. When I moved it to be the last line it all worked out fine. Sorry for the hassle, and keep up the good work btw.
