After updating to IDA Pro 9.2, I encountered an issue when attempting to view the C-tree graph using vds5.py.
When invoking the script I get the following error:
Could not find grapher `qwingraph`. Please check GRAPH_VISUALIZER in ida.cfg
After taking a look at my IDA Pro 9.0, 9.1 and 9.2 my GRAPH_VISUALIZER for my OS, Linux are the same.
The problem is reproducible with any binary I tested under 9.2, while the same workflow functions correctly in both 9.0 and 9.1.
As a temporary workaround, I implemented a custom Python script that exports the graph to a DOT file, which I then visualize outside of IDA using xdot.
Has anyone else encountered this issue in 9.2, or is there a known change in the graph visualization backend that affects qwingraph or the C-tree grapher?
