On the latest Raspberry Pi OS (full) (from 2021-01-11) I installed pulseview on a Raspberry Pi 4 2GB by compiling all components manually.

When creating an empty session and the opening a Binary Decoder Output View
leads to a frozen GUI.
Monitoring the ressources, one sees that the CPU is nearly idling while the RAM gets filled up. At the peak I saw around 82% RAM usage, i.e. 1.6GB
There are some errors:

```
palette support is disabled

```

After the 4 "The largest allowed size is (16777215,16777215)" errors the GUI is completely unresponsive for around 3-5 minutes.
