Adding the following command in intelliJ improved text clarity under
idea64.vmoptions settings:
-Dawt.toolkit.name=WLToolkit
Rational is that im using wayland and to render intelliJ its using middle XWayland compatibility layer which may cause some discrepancy when communicating with Wayland.
The above command will instruct intelliJ to directly use Wayland for rendering, removing the need for middle XWayland layer
