Welcome to 1994.

Yes, this is normal and one of the well known quirks of the Doom engine. It is caused by inaccuracies in the vertex coordinates. Even though ZDoom tries to fix such coordinates it obviously may not be able to eliminate it completely

If it bothers you too much you have 2 choices:

1. Generate compressed nodes for the WAD in question with ZDBSP. These have higher vertex coordinate precision so that these problems are eliminated.
2. Type 'gennodes 1' at the console before starting the WAD. Then ZDoom will rebuild the nodes itself before starting the level.

It doesn't bother me, I was just curious because it's the first time I come across this since I started using Zdoom.

Because that was so extremely obvious from the screenshot.
