Hi,
I have a similar pb with UE4 v 4.24.3 when I use a ‘E’ key to rotate objects.
In first time I used Ubuntu 18.04 with mesa and now I’m runing Ubuntu 19.10. The bug is the same in all case.
I have a AMD GPU and my driver is mesa 20. I install Vulkan packages with this command ‘sudo apt-get install libvulkan1 mesa-vulkan-drivers vulkan-utils’
Some body know the solution ?
