<![CDATA[Sidebar opens only half-size windows (WhatsApp etc.)]]>When clicking on any of the sidebar apps like WhatsApp, Aria etc. this only opens a half-size window, and I cannot access the top half.

I am using Opera One(Version: 106.0.4998.52) (arm64) on a MacBook Pro with MacOS Sonoma 14.2.1 - this effect suddenly appeared a couple of days ago.

Today I have completely re-installed the latest version of Opera One, cleared all preferences in the Application Support folder, and everything that might have been cached.

Alas, same result.

Can anybody give advise on how to fix this?

Hey, Opera team! Do you look into these topics? Can you confirm that the problem is at least addressed?

It looks like the problems appears when the second monitor is bigger than the main one.
Here the sidebar is half cut alt text
Here the sidebar is cut at a third alt text
Now the sidebar is fully shown alt text
I haven't tried to change the second monitor to be the main one, but as I often change opera from screen to screen, this fix works for me now.

And the MacBook is disconnected at least once a day, because I work in different locations.

Anybody have an idea how this issue could be solved?

It happens only when more then one monitor is in use and it happens on secondary one (does not matter if it is built-in macbook screen or external connected via usb-c docking station).
