XRandr reconfiguration reshuffles windows even if not needed (since icewm 3.3.3)

[plomari]

Something like xrandr --output DisplayPort-1 --same-as DisplayPort-0 --auto doesn't change the resolution or desktop size, but it moves around and reorders all windows on the current workspace. Windows in other workspaces are not changed. Tested in icewm 3.3.3. I suspect this is caused by the fix to #713.

This is really inconvenient. I don't want icewm to shuffle my windows even if the screen or desktop resolution changes. Would it be possible to add an option that disables the window moving code? (It should still move the taskbar.)

Setting ArrangeWindowsOnScreenSizeChange=0 helps immediately.

If you say that the taskbar should be moved, do you mean that the position of the output has changed? Doesn't --same-as preserve geometries?

[gijsbers]

Could you give the output of xrandr -q before and after that command?

Perfect. This solves the problem for me.

Almost forgot about this. I just mean in general. In the case I reported, position or resolution don't change. But if they change, I would expect that the taskbar gets moved.

[gijsbers]

Can you test this (with ArrangeWindowsOnScreenSizeChange=1)?

[plomari]

Can you test this (with ArrangeWindowsOnScreenSizeChange=1)?

I can confirm that this doesn't reshuffle the windows anymore in my test case.

[plomari]

I suggest the following changes to the window rearrangement code:

• move windows only if the upper left corner is outside of the usable desktop area
• do this on all workspaces
