MapView causes memory crash (JetsamEvent) on iPhone 16 Pro, works in simulator and desktop

[dragonzo]

Description:
My Kivy app uses kivy-garden/mapview to display OpenStreetMap tiles in a popup. The app works fine on desktop and in the Xcode iOS simulator, but crashes on a real iPhone 16 Pro. The crash log is a JetsamEvent, indicating the app is killed for excessive memory usage.

Steps to Reproduce:

Open a popup with MapView (no markers, overlays, or directions; just basic map tiles).
Wait a few seconds.
App crashes and closes on real device.

What I’ve Tried:

Set cache_dir=None and cache_dir="" in MapView to disable disk caching.
Removed all markers, overlays, and directions code.
Works in simulator, but crashes on real device.

Crash Log:
JetsamEvent shows "freeze_skip_reason:" : "out-of-budget" for my app process (MyApp).

Relevant Code:

mapview = MapView(
    zoom=10,
    lat=center_lat,
    lon=center_lon,
    cache_dir=None,  # Also tried ""
    map_source=https_source
)

Expected Behavior:
MapView should display map tiles without crashing due to memory usage.

Actual Behavior:
App is killed by iOS for exceeding memory budget (JetsamEvent).

Additional Info:

No crash in simulator or desktop.
Only basic MapView, no overlays or markers.
Disabling cache does not help.

Request:
Is there a way to reduce MapView memory usage or fully disable disk/memory caching for iOS?
Any workaround or patch to prevent this crash?

Update on MapView Crash (iPhone 16 Pro):

I tried the following solutions, but the MapView is still crashing on iPhone 16 Pro:

1- Disabled cache in downloader.py

downloader.py

2- Created a very simple MapView that opens on a new screen from a button, without any markers or routes.
Neither solution resolved the issue.
