I noticed a glitch that happens after the display switched off by DPMS (display power management signaling). The device was not suspended (s1) and is still on (s0). After the display is awaken by pressing a key/touching touchpad the old content of the frame buffer is used until the device is put into S1 after that it behaves normally again. Until then the display only updates its contents once after each tap on the touchpad. This glitch does not happen with enable_psr=0.</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> </ul> </body> </html>
