Sway/Wayland black screen flickering

[batGnat]

Probably a wayland related issue, Audio works fine, but window is black with some occasional flickering.
If I change to XFCE it works fine.
Any ideas on how to get it working?

Running Arch.

Found that the following will force QT5 to X11, and it works.
chiaki -platform xcb

Is the more permanent solution a chiaki issue, or a QT5 wayland upstream issue?

[lovenemesis]

Under GNOME 3.36 with Wayland it's simply just black screen.

However, your tips to force Qt5 to X11 works.

Also black screen on Weston (8.0.0) and GNOME 3.36 on Wayland. (chiaki 1.2.0)
