Do you regularly switch between computers? I have this happen to me whenever I swap computers and there is always a different graphics setting/resolution between them. Once it’s sorted itself out I’m good for the remainder of the session.
Entropia has changed too since when you were using the old pc, more items ingame with more detailed models. A Fast SSD might help with loading times. But its not a guarantee. Eu is on my pc on a pcie gen4 ssd with 32gb ram and my storage takes a while to load too sometimes, or when entering a service center i fall though the map until the interior is loaded. The Cryengine shows its age here, that it wasnt developed to be used in a MMO but rather for singleplayer shooters doesnt help here either. There is hope that such things like loadingtimes will be improved with the next big graphics update, but that also will come with a higher tax on the hardware itself. Be prepared to not see much improvement since the overall higher quality we will much likely see eats away cpu and gpu speed.

That must be something related to the network traffic then. Data gets sent via UDP, which is simpler and faster than TCP, but doesn't provide the validity checks. So failed packets are dropped and aren't (re)sent again automatically. Whatever caused the data to be sent must be done again. Obviously logging out and in will do that, but also like playing for several minutes and checking again may "fix" the display.
You are, joking, right?
What everyone can do no matter what game is to go to a streaming service (Twitch, ...) or video hoster (YouTube, ...) and find streamers playing and live videos of that game. While saying that it's important to watch those with lots of viewers/views and top-notch equipment and also those with hardly any viewers/views and bad equipment. This helps to understand what the problem can be.
