Opera One - broken popup menus

After update to Opera One in Lubuntu (20.04.6 to 22.04.4 system update) I have some strange popup menu behavior (on screenshot) - square of black color under popup menu. It persists in Private mode and on settings page, so it's not extension, it's new Opera One feature.
Opera version - 108.0.5067.20 (Chromium:122.0.6261.95)
video driver - amdgpu. Card - AMD RX5700 (Games works). I use X11 (xorg).
How google or fix this?

It's GTK 4 issue, see analog in Chrome and Telegram (save dialog).
May be exist some plugin, what disables rounded menus, or flag, what changes rendering policy for menus?

Delete wayland, not helped. It's GTK and Opera's rounded menu issue:

Please say anybody, how to change menus to not-rounded? May be some addon? I not need compositor in my system.

@count0 Rounded corners are part of the Opera One design, I don't think it can be changed.

I changed Open-Save dialogs (that also has rounded menus with ugly black squares) by deleting xdg-desktop-portal-gnome and installing xdg-desktop-portal-kde. Reboot required to apply.
Theme for qt - managed to dark and square (Qogir-kde-master) with kvantummanager, and

export QT_STYLE_OVERRIDE=kvantum > ~/.profile

Telegram and Opera dialogs now fine. Only context menu remains. In Chrome

--disable-direct-composition --disable-direct-composition-video-overlays

startup flags helps make it square.

Fresh Bug in Chromium:

Solution:
"Don't render menu shadows when there's no compositor"
Waiting for Opera update.

@count0 The bug you sent runs on Chromium 118, while the latest Opera Stable runs on Chromium 122.

But it could also be a feature flag that opera changed
