[iOS] Canvas elements disappear when an app is put in the App Switcher when the Canvas has "ScreenSpace - Camera" set as the Render Mode
How to reproduce:
1. Open the “iOSBlackScreenAgain.zip“ project
2. Open the “NoCanvas“ scene
3. Build for iOS
4. Open the “Unity-iPhone.xcodeproj“ in Xcode
5. Build to a device
6. Open the app
7. Press the “Set Canvas to ScreenSpace - Camera“ button
8. Press the “Set Skybox“ button
9. Swipe up to enter the App Switcher
10. Repeat steps 8 and 9 with buttons (“Set Solid Color“, “Set Depth Only“, “Set Dont Clear“)
Expected result: The app preview shows the valid snapshot (launch screen or last frame)
Actual result: The Canvas elements disappear
Reproducible with: 6000.0.56f1, 6000.2.1f1, 6000.3.0a5
Not reproducible with: 6000.0.55f1
Reproducible environment: macOS 15.6 (M4 Max)
Not reproducible environment: No other environment tested
Reproducible with these devices:
VLNQA00626, iPhone 16 (MYE73QN/A), CPU: Apple A18 Pro, GPU: Apple designed, OS: 18.5
VLNQA00358, iPhone 12 (MGJ93ET/A), CPU: Apple A14 Bionic, OS: 14.1
VLNQA00416, iPhone 13 Pro (MLVA3ET/A), CPU: Apple A15 Bionic, OS: 16.1.1
VLNQA00535, iPhone XS (MT9F2ET/A), CPU: Apple A12 Bionic, OS: 17.6.1
Not reproducible with these devices:
VLNQA00494, iPhone 14 Pro Max (MQ9T3PX/A), CPU: Apple A16 Bionic, OS: 16.3.1
VLNQA00232, iPhone 8 Plus (MQ8M2ET/A), CPU: Apple A11 Bionic, OS: 16.7.10
Notes:
- It must be Built-In Render Pipeline to reproduce the issue, it does not reproduce with URP, because it is dependent on Camera Settings
- The issue is only reproducible if Canvas is set to “ScreenSpace - Camera”
- Changing “Player Settings > Render Extra Frame on Pause” has no effect on reproduction

"It must be Built-In Render Pipeline to reproduce the issue, it does not reproduce with URP, because it is dependent on Camera Settings"
For me, it is also reproducible with URP. It looks particularly unattractive when IAPs are made and then the entire canvas (screen space camera) disappears.

The problem is slightly more severe - it's not just when the app is minimized to App Switcher.
The issue is also seen when, for example, a system notification permission popup is shown (app loses focus).
