fuse on Debian buster malfunctioning

[Phil Reynolds]

Whether Debian's packages or my own compile, I am finding that fuse
malfunctions - triple size filter in gtk produces an image too big for
the window, and even with double size, some areas of the screen are
occasionally whited out or have unexpected text in them.

Is this a known issue and is there a fix?

Ok, I uploaded a workaround to Debian that defaults to X11 over Wayland when the former is available.

This should be the least annoying option for users until we fix the Wayland problems completely.

Are you using Wayland ? If so, can you try with X.org and see if that makes a difference ?

[Phil Reynolds]

Confirmed. Problem there only in Wayland.

Ok, thanks.

It's not the first time that someone reports problems with Fuse and Wayland, I actually had to disable the Wayland socket in the Flatpak build for this reason (see https://github.com/flathub/net.sf.fuse_emulator/issues/1 and https://bugs.debian.org/872994).

I haven't had the time yet to debug the problem and see what is really going on, but I suppose that a workaround for Wayland users would be to unset the WAYLAND_DISPLAY environment variable before running Fuse, e.g.

$ WAYLAND_DISPLAY="" fuse

or

$ unset WAYLAND_DISPLAY
$ fuse

or

$ GDK_BACKEND=x11 fuse

I forgot: we also have a bug about this in the Fuse bug tracker: https://sourceforge.net/p/fuse-emulator/bugs/367/

Major efforts in fixing problems on Wayland have been made in [feature-requests:#135]. Any feedback is welcome.
