File this as a new bug and provide a sample .blend as well. Mention the following bug in your report: https://developer.blender.org/T69853

Fix T69853: Object orientation is wrong with some AMD deprecated drivers.

but for the moment if you want it to work well also on linux, you have to start blender with

./blender --debug-gpu-force-workarounds

for those on some GPUs Radeon HD has problems with shadows and lights in eevee
must start blender with

R600_DEBUG=nosb ./blender --debug-gpu-force-workarounds
