Light flicker in Subterranean Chart + cannot click any node (Delve – Mirage League)

Issue description:
Since the start of the new league, opening the Subterranean Chart in Delve causes the background to flicker rapidly. In addition, clicking any node does nothing, no movement, no interaction, no error message.
Steps to reproduce:
- Enter a Delve mine.
- Open the Subterranean Chart.
- Notice the background flickering.
- Click any node.
Expected behaviour:
The background should remain stable, and clicking a node should select it and allow path planning.
Actual behaviour:
The background flickers and nodes do not respond to clicks.
Additional info:
- The issue happens consistently after traveling 1 or 2 nodes
- (Optional: add your resolution, fullscreen/windowed mode, GPU, driver version, etc.)
- 3440x1440 resolution
- directx12
- 9070xt gpu

This has been happening to me as well. I either have to relog or travel back to hideout and talk to Niko in my hideout to go to the next node. Ive ended up just given up delving. Hopefully its fixed soon.

It happens far less frequently now.
