- Channel remapping dropdown in the Terrain Layer does not open when clicked on the title
- The Editor freezes indefinitely when a large number of elements are entered in the Subgraphs or Categories lists
- Some Visual Effects package Assets links to documentation are not working
- Heatmap asset’s documentation button in the Inspector window leads to “Sorry... that page seems to be missing!” page when clicked
- Crash on MonoBehaviour::CallMethodIfAvailable when performing various actions
Resolution Note:
Too risky and low impact to fix. This is a legacy inspector made with IMGUI and it's automatically drawn, adding customization would be complex. Also, Custom Fonts should not have 9999+ rects.
