Research direction

Reproduce the issue using split graph and linear views, then undefine a selected code range with U and compare navigation in both views. Trace the graph/linear synchronization entry points for undefining code; done means the graph removes the affected code and both views continue to navigate to the same locations.

Description

Version and Platform (required):

Binary Ninja Version: 5.4.10427 dev
Edition: Ultimate
OS: macOS VM
OS Version: 27.0
CPU Architecture: m3

Bug Description:
If you undefine code inside of the linear view, they will not be sync'd to the graph display and instead it will keep the old disassembly.

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

Split graph and linear views.
Select a random part of the code
Press U for undefining it, turning the assembly into bytes
Click around. If you click around linear, it will not move the graph. If you click in the graph, it will move the linear view to wherever the old instruction used to be.

Expected Behavior:
Expected behavior is that the graph would lose that portion of the code and would remain sync'd with changes to the assembly.
