Maximized windows appear either fully white or only are updating in half

With the new titlebar enabled, maximization gives a 100% transparent, non-existent window i.e. I am seeing and interacting with desktop.

Geometry appears to be on similar location, which would mean that the window should be there

I'm pretty sure this is something to do with your unusual desktop geometry.

[stdedos]

I would gladly agree; however, I have been running and using these versions before. What could have possibly happened over the weekend, given that both client and server were unused and un-updated?

Well, that information is new. Have you tried restarting the client with the headerbar disabled?

Replying to Antoine Martin:

I said For any version r26160+. That means both with, and without the new headerbar, and yes, I have also tried with the header bar disabled. It seems to me, that with the headerbar is a bit better (but still far from "easily interactable").

Of course, there is the option to work with "non-maximized" windows, but that feels very unproductive to me.

[stdedos]

And, as miraculously as this appeared, it disappeared today (used r26503, with the custom headerbar)

[Antoine Martin]

Can I close this?

[stdedos]

As you wish. I haven't seen it, but I am also on 4.0.2 client 😕
