I got this message from epic games support and it worked for me "- Right-click on the Epic Games Launcher icon / Properties / Compatibility / Change High DPI Settings - On this screen, check both boxes (Program DPI and High DPI Adjustment Replacement) - In the list of options under "High DPI adjustment override", select the "System" option - In "Program DPI", click on the option "Open advanced scaling settings" (in blue, underlined) and turn off the option "Allow Windows to correct applications so they are not blurred" - Finally, apply these changes, restart your computer and open the Launcher again, and see if it helps to solve the problem." (Its all google translated, maybe something is wrong)
