Hi,
Thanks for your answer. We made a build without this part, but unfortunately it seems it didn’t work for our client.
Upon different tries, he also had the following traces in demsh (similar ones multiple times) :
[62698.920018] radeon 0000:01:00.0: ring 4 stalled for more than 10220msec
Resulting in a crash of sddm (he is under KDE), or a freeze or kill of the game.
One of our client has a crash upon launching our game under linux (Ubuntu) with an AMD 290X.
This happens either with opengl 3 or 4.
Our main menu shows no 3D content, just flat UMG images and buttons.
Does anyone has any clue of where to look based on the information below? (Is this a known bug, is it related to bad drivers, can this be due from our code despites it shows only ue4 engine code, etc…)
Thanks.
Here is its configuration:
Ubuntu zesty AMD FX-4100 32 Go de ram
AMD 290X OpenGL renderer string:
Gallium 0.4 on AMD HAWAII (DRM 2.49.0
/ 4.10.0-28-generic, LLVM 4.0.0)
OpenGL core profile version string:
4.5 (Core Profile) Mesa 17.0.3 Linux 4.10.0-28-generic X86-64 #32-Ubuntu SMP Fri Jun 30 05:32:18 UTC 2017
Here is the detailed error log:

This seems like the problem described here. Please delete or comment out creation of the linker script from LinuxToolChain.cs and rebuild the executable.
