[sddm] SDDM screen doesn't display if a mouse move is not executed

Hello,

since a recent "pacman -Syu" ( 25 june ) I notice a problem on boot with SDDM :

the boot with systemd is OK, no errors, but the graphical screen for SDDM doesn't come automatically, the display is still on "console mode" with systemd messages ( green [OK] lines ),

I have to move the mouse in order to display SDDM screen, it's not normal, it seems that the system waits a mouse move before displaying SDDM graphical screen,

the same bug occurs when I want to logout my plasma session, the SDDM screen doesn't display automatically, I have to move the mouse in order to display SDDM log screen,

I use the oxygen theme, plasma-integration-framework, oxygen-icons, I don't use breeze theme,

I suspect a problem with sddm, or qt5 libs

the only error I see about Qt in dmesg is :

$ dmesg | grep Qt
[ 699.495056] kactivitymanage[637]: segfault at 7f5edd565cf0 ip 00007f5edd57dce1 sp 00007ffc4255d7c8 error 4 in libQt5Sql.so.5.7.0[7f5edd567000+46000]

my configuration :
- CPU : intel dual core E6800 3.3 Ghz
- graphic card : amd radeon HD4650 Pcie with the radeon driver
- motherboard : gigabyte GA-P31-DS3L ( intel P31 chipset )
- 4 Gb ram

Additional info:
* package version(s) sddm 0.13.0-2, qt5-base 5.7.0-1, systemd 230-5, xorg-server 1.18.3-2, linux 4.6.2-1

Re: [sddm] SDDM screen doesn't display if a mouse move is not executed

I found the explanation : it was a broken SDDM theme, the "Elarun" theme,

If I choose another SDDM theme ( like "Brise" ) then all is Ok,

so there is a broken theme in SDDM since the upgrade of Qt5 ( 25 june )
