Redraw bug: dragging groups with text layers with 'Blend RGB colors using gamma 1" enabled

Top: a simple text layer within a group
Bottom: the same layer after moving the group with the move tool.
+ happens ONLY if moving the group with the layer, moving the text layer itself works fine
+ nudging the group with the keyboard works fine
+ happens regardless of Font, weight, antialiasing etc
WHEN:
+ if 'Blend RGB Colors Using Gamma 1' option is checked in Color Settings
+ even with the above option disabled, if 'Blend Text Colors Using Gamma' is checked, regardless of the gamma value, the effect is there, barely visible
Adobe, fix this!
PC, Windows 10, latest video drivers.
