I don't think Avalonia support this effect, but I also can't reproduce any crash on 11.2.4.
Do you have any stacktraces or specific repro projects?

Publish app with partial triming

Just in case if it related to windows accessibility APIs, can you try with nightly builds? These have better support for accessibility when app is trimmed.

hi @maxkatz6

thank you for your reply

The problem has been resolved after updating to the 11.3.999-cibuild0054958-alpha version, which is great. But problem still exists in the 11.3.999-cibuild0052371-alpha ( the first version of 11.3.999)

In versions 11.1.x and 11.2.x, this crash problem indeed occurs 100% <TrimMode>partial</TrimMode>. There are two scenarios for testing:

1. It is the modification of the system text cursor color as mentioned before.
2. Install third - party software with word - selection/highlight - translation functions (such as translation software, like https://fanyi.youdao.com/). When you select text for translation in the system, a crash will also occur.

We can only obtain information about the crash from the system logs, but it only tells us that the application has crashed.

When will version 11.3 be released? Currently, this situation is quite common (mainly due to the second point above). We are even considering updating to the 11.3.999-cibuild0054958-alpha to solve this problem, but we don't know what new impacts it may bring.

Thank you
