Package: sddm Version: 0.15.0-1 Severity: important Dear Maintainer,
After a recent upgrade sddm login is heavly flickering. it gets a white portion and then repaint the theme. The screen stops flickering only after the username and password had been entered. No flickering happen after plasma is loaded (KDE screen) , or in differet VT. the flickering comes back if a new session is open via plasma that start sddm login screen on a different VT. I have tried Maldivians and breeze themes (both have the same issue). There are reports in Gentoo forms that suggested to have libdrm2.4.80 but I have ibdrm2_2.4.84-2_amd64.deb installed. extra details : 4.13.0-1-amd64 plasmashell 5.10.5 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc.
