Probably worth filing a bug over at gitlab for the modesetting > ddx as well, e.g. it is probably sensible to use the highest precision gamma > tables regardless of frontbuffer depth. The approach I took with the intel ddx was stick with the legacy 8bpc LUT for <=8bpc screen. The benefit being that we know it's not an interpolated gamma mode and so directcolor type of stuff keeps working. The higher precision gamma mode we expose may or may not be interpolated depending on the platform. Shouldn't be too difficult for someone to port over the intel ddx gamma code to the modesetting ddx.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
