Could be a problem with the new render hack detection. Is this the first map?

Yes, Winnowing Hall. Starting Deathkings leads to similar result (map Ruined Village)

Hmm, I just played Hexen and Deathkings with the latest unstable and everything was looking ok.
Could you attach your doomsday.out log?

- File doomsday.out doomsday.out added
Forgot to mention that I did it with 2 addons enabled: XARP 0.13 and Neural Texture pack (the latter being the first in the load list), in XARP I disabled all textures.

Still cannot reproduce the issue.
Did you use one of the prebuilt binaries (Flatpak, dengine.net DEB/RPM, or PPA)?
I just tried the latest unstable Flatpak build, and it works correctly for me.

I'm using RPM doomsday-2.3.0_build3276-1.x86_64
The problem occurs without addons too.

Trying to warp to map26 crashes doomsday. Stable 2.2 works fine.

Does the Flatpak unstable build work for you?
I'm using Fedora 23 to build the RPM packages, and it has a rather old gcc (5.3.1). That is one potential source of issues...

In flatpak version problem does not occur. However I can't figure out how to start the application properly, which permissions to give. It does not allow to select sound output device (the list is empty) and music is played with a lot of static (FMOD + FluidSynth, 64 channels).

Tested RPM 3278, same thing happens, and with Heretic too. Seems to affect every game.

I think we should try a build with a newer version Fedora, so it has a more up-to-date compiler. Probably the Fedora builder could be bumped a few versions up from 23. Not sure when I'll have the time to do this, though.

- Subject changed from [Hexen] geometry is garbled to Map geometry is garbled using GCC 5 on Fedora
- Category changed from Regression to Defect
- Priority changed from High to Low
Potentially an optimization related bug with GCC 5. A possible workaround would be to selectively disable some GCC optimization flags, but it's more productive to switch to a newer release of Fedora on the RPM builder.

Hi! I found similar problems when using doomsday-bin from AUR in archlinux beacuase the script use the official RPM package.
https://aur.archlinux.org/packages/doomsday-bin/
I found a solution for compiling in Archlinux changing the assimp included in sources to assimp 5.0.1-3.
https://aur.archlinux.org/packages/doomsday/
I wish this could help to linux users.

Hi again! There is still some minor bugs, pink demons model with DHMP are not over floor, they are inside floor textures. Solved when compiling doomsday with assimp 4.1. Regards!
