Description Henrik Hudson 2025-03-10 17:06:11 UTC
This was working fine with 6.2.x and even 6.3.0 (if I remember right), but it's gotten worse with 6.3.1 and now 6.3.2 is really bad. I run dual monitors. They're identical monitors and both are hooked up via HDMI. Dell U2719D . When the monitors sleep and I come back all the windows are either a) re-sized or b) switched monitor or both.

STEPS TO REPRODUCE
Have dual monitors and let them sleep and wake up.

OBSERVED RESULT
windows are all over the place.

EXPECTED RESULT
windows stay where they were.

This was the same problem in 6.1, but somewhere in 6.2.x  it got fixed and was working great.

I'm only using the AMD / ATI card. It is DP out, but using mini-DP -> HDMI cables to use HDMI on the monitor side. Sorry, forgot the card side was DP.
