# kwin — amdgpu advertises DRM_FORMAT_RGBA8888 in rgb_formats[] and
# overlay_formats[], but fill_plane_buffer_attributes() has no case for it, so
# the atomic commit fails with "Unsupported screen format RA24" and KWin
# retries until the desktop wedges. Forcing overlays on keeps KWin on the
# primary plane. KWin parses these as "value == 1", so 0 is not false, it is
# unset; the greeter's own unit sets 0 for that reason. Direct scanout stays
# enabled on purpose: it is what lets fullscreen video and games bypass the
# compositor, and the overlay path above already covers this bug.
# Gated on the Radeon dGPU so laptops and Intel-only machines are untouched.
# Drop this when upstream adds the missing case.
