I had the same issue with KDE Plasma5 after updating of mesa ports to 20.2.3,
cp /usr/local/share/drirc.d/00-mesa-defaults.conf ~/.drirc
fixed my issue with OpenGL compositing in KDE Plasma 5
Some technical details:
Current 13.0 amd64
modeset(0): glamor X acceleration enabled on Mesa Intel(R) UHD Graphics 620
(KBL GT2) ( Kaby Lake )
modeset(0): [DRI2] Setup complete
modeset(0): [DRI2] DRI driver: iris
modeset(0): [DRI2] VDPAU driver: va_gl

I suspect that KDE Plasma 5 expect some hints from mesa, but due to unknown
reasons iris driver can not get them from
/usr/local/share/drirc.d/00-mesa-defaults.conf
