Transparent fullscreen windows render black background
- Archlinux and Fedora
- Mutter >= 43.1
Applications that use background transparency in fullscreen mode (i.e. F11) render a black area instead of showing the wallpaper. This affects the terminals which apply background transparency through VTE3.
I'm not sure but guess that window-actor/wayland: Draw black background for fullscreen windows caused that.
Thank you for your work
PS: Not every VTE3-based terminal provides transparency by default. At least gnome-terminal requires additional patches. Fedora ships them by default. On Arch you can use another terminal like Tilix or the AUR package which I maintain from below.
Steps to reproduce
- Install tilix, gnome-terminal (Fedora) or gnome-terminal-transparency (Arch)
- Set background transparency in the preferences (profile -> colors), which works in windowed mode
- Switch to fullscreen i.e. press
What did Mutter do that was unexpected?
Renders black background.
What did you expect to happen
Transparent background according to the setting.
