Hello m'dears.

Currently experiencing the same bug here on wayland.... tried so many different things. But no luck. But unfortunately it didn't change anything. At no time does latte appear (after restarting latte on the cmdline and with the correct flags). I can attach the --debug log here but it's probably not going to help.

If it is any small clue, IDK. But when running latte from the cmdline it stops logging output and never prints anything after the screens / displays detection bit. And then if I try to interrupt latte-dock process by sending a ctrl+C on the keyboard (SIGINT). That is ignored. So then I have to ctrl+z and forcibly kill it off. So IDK if that means latte is actually hung and crashed process. Or if that is just normal correct running program behaviour of it to ignore ctrl+c....

Things I have tried

* Thoroughly updating my system, including re-installing the nvidia proprietary drivers AND libmesa ones (AND kernel). Check.
* Recompiled Latte using today's `./install.sh` from the git repo? Check.
* Try latte on gnome wayland instead of plasma? Check. (but it segfaults on gnome. So was no help)
* Unplug dual displays and reboot? On either monitor has no effect. Latte is still completely AFK. Check.
* Add environment var `QT_QPA_PLATFORM=wayland` ? Check. No difference.

Overall situation seems difficult to probe or get a better understand of, (for myself here). Because it might in fact not be latte itself, but some other bugs in either qt5 libraries, or in wayland (in kwin). Or in the nvidia proprietary drivers 510. Since there's certainly other things going on and causing other types of bugs within the wayland session. Even when Latte is not running.

And this is supposed to have been fixed recently? This specific bug?

My system configuration:

* Ubuntu 22.04 (upgraded from 21.10, 21.04, 20.04, etc etc)
* All of the qt5 and other libraries as per ubuntu 22.04 distro
* Plasma version `plasma-desktop/jammy,jammy,now 4:5.24.5-0ubuntu1~ubuntu22.04~ppa1 amd64 [installed]` (=5.24.5, from kde backports?)
* nvidia-driver-510 verison `nvidia/510.73.05`
* Kernel `5.17.11-xanmod1 #0~git20220525.9ffe6c5`
* Latte version: `lattedock 0.10.77`
* GPU = nvidia gt1030 Pascal generation (this prevents installing the new open source nvidia drivers)
* MESA = `mesa-vdpau-drivers/jammy,now 22.1.0+git2205261808.f8b312559ba~j~mesarc0`

Other main bug on wayland here: The plasma panels (not latte) are slow and unresponsive. Like you right click on the desktop and it's laggy / gets progressively less responsive. IDK if that would affect Latte Dock. However other regular applications are mostly not being affected. There is a suspicion of 'nvidia timers bug' existing on closed source nvidia drivers? However the problem there is that it's kernele non-GPL symbols (cannot be fixed by nvidia?). Since the nvidia open source driver does not support cards like mine (pascal), anything older than 2000 series nvidia gpus. Cannot try the open source driver to eliminate that.

Again, no idea if such other kde bug would affect Latte adversely in this way. And no idea why removing 2nd display works for other guy here. But not for myself. Or if it's indeed some seperate bug here in latte dock. Which maybe was not fully fixed?

Anyhow that's my report, and heres a link to my logfile, https://gist.github.com/dreamcat4/09dda9074fed6b2270ef4273b9f73f0a
