Fail to init video driver

[fgsoftware1]

when i open the app it opens the window but canvas is black and the following error appears on the terminal:

MESA-INTEL: warning: Haswell Vulkan support is incomplete
libva error: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so init failed

doing this seems to solve the error but black screen still:

export LIBVA_DRIVER_NAME=i965
export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri/
