U2717D, two, DDM bug

Question

Hello,OS: Windows 10Monitors: Two U2717D monitors horizontal, one next to the secondI would like to report bug related with DDM (Dell Display Manager). The bug has case when on right U2717D (primary U2717D in Windows display settings) in DDM full screen layout is chosen, and extend any application (e.g. chrome or slack), to full screen on that U2717D (through maximize icon in that window). Then use command CTRL+WINDOWS+RIGHT_ARROW to change Windows virtual desktop and then CTRL+WINDOWS+LEFT_ARROW to back to first one. After second command when first virtual desktop has come then maximized application changing size to lower, and a little bit shifted. That is very annoying when often changing virtual desktops ;/ That case have no place when using DDM full screen instead of application maximize button.Best regards.

Yes. I understand it is already fixed, and you will see it in the next release. (RC is here if you cannot wait.)

I don't see that.

1. Two identical monitors, side by side, with primary on the right

2. EA is on, on both monitors and on both virtual desktops

3. Open Chrome on right monitor, then click maximize button

4. Ctrl+Win+Right to switch virtual desktops

5. Ctrl+Win+Left to switch virtual desktop back

Chrome is still maximized on right monitor

What did I miss?

Do you have installed and running DDM?And chosen full screen layout on right monitor in DDM?

swamped207 · Answer

Yes, to both questions. Using two identical U24s instead of U2717s, but that should not matter. Post your DDM diagnostic report; maybe it will provide a clue.

swamped207 · Answer

The log is incomplete, which can happen if DDM has been running for a while. Please do the following:

1. Close DDM if its running

2. Start DDM from the Start menu

3. Save the diagnostic log and post it.

swamped207 · Answer

Never mind that last. I see it. Initially I understood you had maximized the window *inside* EA (predefined layout #1), but its actually maximized in Windows.

Ravcio · Answer

ohh. ok. I see.. i made type 'window' instead of 'Windows', my bad. Sorry. Anyway, do you can now recreate that bug?
