Title: Assertion on closing codeblocks due to wxWidgets 3.3
Post by: christo on August 16, 2026, 07:34:05 am

There is a regression in wxWidgets causing assertion window on closing codeblocks if the project tree is expanded and is big.

Code

../src/generic/treectlg.cpp(1539): assert "IsVisible(item)" failed in GetNextVisible(): this item itself should be visible

I've reported it to wxWidgets project and fix is identified. https://github.com/wxWidgets/wxWidgets/issues/26839
