lxqt-config-monitor not restoring multi-display configuration

[fenugrec]

I'm having possibly a few issues with multi-display configs, possibly same root cause.

Expected Behavior

After display blanking and waking up, multi-display config should be restored as it was.

Current Behavior

On wakeup :

• all windows that were on secondary monitor are now on the primary display
• one monitor (on DVI), that should be 1920x1080, now is set to 1024x768
• lxqt-config-monitor reports this DVI monitor as "1920x1080", which is wrong and disagrees with xrandr --query

Steps to Reproduce (for bugs)

1. configure two monitors with one primary (HDMI) and one that "extends another display"
2. let computer idle and turn off displays
3. wake up by moving mouse

Context

This used to work fine with a slightly different monitor setup (same DVI monitor , but the other one was DP) , so the problem is probably not just a regression.

I realize this may be difficult to reproduce, but I'm not sure what type of debugging info would be useful to provide.

slight update - connecting the HDMI monitor into HDMI-A-0 instead of HDMI-A-1 , almost same behaviour regarding window placement (everything is moved to the DVI monitor), but at least now both monitors are set to the correct resolution.
Happens both with openbox and icewm as WM.
