Since this is a Linux install, note that we require the proprietary driver from AMD or NVIDIA to run X-Plane. You may be able to get X-Plane to run on the Mesa/Gallium driver with an Intel GPU, but this is unsupported. We absolutely do not support the fully open source drivers for AMD and NVIDIA.
Otherwise, we see this issue with Fly Inside as they modify our default files to run. If you use this add on, you will need to contact them for a fix.
