Steps to Reproduce

We have error report in Sentry that saying Application Specific Information: UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={810, 1080}, scale=2.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert. when we look at the thread that cause it also contain stack trace saying Sentry_Maui_Sentry_Maui_Internal_ScreenshotAttachmentContent__c__GetStreamb__2_1. I am not really sure actually if this is caused by Sentry or not but we do attach the attachment on sentry so it might be the cause. Here I also attach the crash report dbc983a62a9a4fb7bdef3f940462a18d-symbolicated.crash.zip

Expected Result

App should not crash or throwing exception

Actual Result

App throwing exception

Solution

The root cause is a problem with the MAUI ScreenshotImplementation class. Ideally this would be addressed in the MAUI repo then:

• Replace obsolete iOS BeginImageContextWithOptions dotnet/maui#28682

For the time being, we've wrapped our usage of this API in a try..catch/log block. In these instances, no screenshot will be captured but at least the application won't crash.

• Prevent application crashes from MAUI ScreenshotImplementation #4069

@albilaga are you able to reproduce this issue? If so, you could try setting options.AttachScreenshot = false when initialising Sentry to see if this has any impact? That would help narrow don't whether it might be a Sentry issue or not.

@jamescrosswell unfortunately not but we are setting the AttachScreenshot = false now and will monitoring for next release of our app

Hi @jamescrosswell after setting AttachScreenshot = false we don't see this error anymore so it might be related

@jamescrosswell that option just forwards to native code, right? If so, it may be worth moving the issue to sentry-cocoa.

My two cents: it may be due to memory pressure so the device is unable to allocate desired screenshot size.
