Ok, I found the Answer to my odd EpicLauncher distortion.
I had the Windows display setting “Scale and layout” for fonts set to 125% and while I had the screen resolution at 1680x1050 or 1920x1080 the EpicLauncher would be distorted.
When I put the windows10 settings “Scale and layout” back to 100% the EpicLauncher was fixed.
Must be an AMD Embedded Radeon GPU driver problem.
Hope this helps others
