No actual data shown even though it is flowing in and displayed in the left column

Problem description

I'm consuming JSON-formatted IMU data via ZMQ. The subscription process works just fine, and I've used PlotJuggler within the same project successfully before. However all of a sudden I do not get any actual graphs shown when dragging/dropping values into the view pane, even though I see the values update in the Timeseries List. The graphs are rendering with the time axis moving, just no data shown.

Every now and then I see some flickering in the graph views, but it doesn't look like the data, more like a rendering glitch.

Answer these questions (or I will ignore your issue)

1. I'm using Linux (ubuntu 22.40, Wayland, KDE), freshly built PJ version 3.9.2
2. Compile and try the latest version in the main branch and check if the problem persists -> Did that, problem persists. f4f9d4192aee87fefac205fd48285b407f97e0b9
3. Check if the problem can be reproduced using the dummy data created by the command line argument "-t" or one of the files in the folder "datasamples". -> Did that, -t. Problem persists. I can see the data changing, but dragging it into the view pane doesn't make it show up, only scroll the timeline

Ok, I rummaged through the dependencies, and found OpenGL. Disabled it. It works. Any hint as to what could be the root cause here?

Also disabling it only showed an effect after restart. Maybe worth a MessageBox? Otherwise users might be confused as to why it's not having an immediate effect.
