When using wlvncc to connect, wayvnc reports an error

[fxzxmicah]

ERROR: ../src/server.c: 1291: Failed to encode current frame

wlvncc is built on fedora.

There needs to be much more context here for this to be useful.

The error was resolved using parameter -e tight, but the displayed screen remains black. Normal use can only be achieved after using the parameter -s. So this may be a wlvncc issue. When the screen remains black, there are the following error:

Oops, back-buffer is still attached.

You're probably running neatvnc v0.8.1 and it's failing to encode using h.264 and not falling back to the next encoding. This is fixed in neatvnc master. It would have been useful to also get the version info like suggested by the issue template.

GPU mode on wlvncc might fail when people have multiple GPUs on the system. It doesn't know how to select the right one, but like it says in the readme, wlvncc not considered production grade software.

OK, thanks.
