Godot 4.2 loads to black screen on Arch, Wayland (xWayland), and NVidia GPU, but works with --single-window

[mmmmmmmmmmmmmmmmmmmdonuts]

Tested versions

Godot 4.2 Release

System information

Arch Linux

Issue description

• This is occurring on Arch Linux (latest update), KDE Plasma 5.27 (latest), Wayland Session, nvidia proprietary driver
• if you run it strictly as an executable, an xWayland window opens and the contents are black. The X in the right corner won't work either
• If you run godot with the --single-window parameter, godot project manager opens as expected

Steps to reproduce

execute godot4.2 as above

Minimal reproduction project (MRP)

Simply download the editor and execute

can confirm. have the exact same issue.

• Related to Black rectangles over new UI elements when using Wayland #81732.

Can you reproduce this on 4.1.3?

That said, NVIDIA + Wayland is a notoriously buggy combination, even with recent drivers. Consider using a X11 session instead.

See under 2.1

This issue has been resolved in Godot 4.1.1. [2] This issue seems to have recurred in Godot 4.2 [3]

Just downloaded Godot 4.1.3 and 4.1.1 and for me on both versions the similar issues persist. Also on single window mode on all the versions (including the newest 4.2.1) the editor window flickers very often when using it and at the same time is unresponsive. Unresponsive means that when I click on something I have to first "artificially" use the scroll wheel that the editor window refreshes and shows what I just clicked.

With X11 all versions work just fine. This is a bug in wayland/xwayland

Well, before I tried rebooting etc etc and it kept happening, but now I cannot reproduce it even on 4.2 ¯_(ツ)_/¯ . I did do a pacman -Syu to install a few things so it's possible something in addition was updated and fixed it.

Still happens to me with:
OS: Arch Linux x86_64
Kernel: 6.7.1-lqx1-1-lqx
DE: GNOME 45.3 Wayland
GPU: NVIDIA GeForce RTX 2060 SUPER
Driver Version: 545.29.06

Using --single-window fixes the problem but the editor keeps showing black frames and some tooltips also are shown black

I still have a problem on NVidia with Wayland. I found a fix that works "fine" and it's by enabling the option "Update continuously" (from the top right spinner). I have tried with 4.2 and all the dev version on 4.3.
OS: Fedora 39
Kernel: 6.7.9
DE: Gnome 45.3 Wayland
GPU: NVIDIA GeForce GTX 960
Driver version: 550.54.14

Update:
I upgraded to Fedora 40 which enabled explicit sync. That seems to finally have fixed overall the issue running Godot on Wayland with an NVIDIA graphics card, even by having the spinner updating only with "change".
In order to enjoy explicit sync, various components on the desktop need to be updated, nvidia drivers to v555, mesa 24.1, XWayland 24.1, GNOME 46.1 etc.

OS: Fedora 40
Kernel: 6.8.10

GPU: NVIDIA GeForce GTX 960
Driver version: 555.42.02

@mmmmmmmmmmmmmmmmmmmdonuts Can you (or anyone else) still reproduce this bug in Godot 4.4.1 or any later release?

[mmmmmmmmmmmmmmmmmmmdonuts]

My sincere apologies. I gave up on Linux after having a lot of little other unrelated issues. I've been meaning to go back to Fedora 42 now that it seems Plasma and NVidia are in a better place (and some of my work apps like Citirx seem to have been fixed). I can get back to you once I do that but I've been putting it off. If you need to close this that's fine with me. I can open a new one if I ever manage to go back and the issue persists. Thanks for working on it!

[Cate95]

I did a quick test and couldn't reproduce the issue—it seems to be resolved. Thanks! That said, I'm not really able to dig into it thoroughly right now. Maybe someone else can take a closer look?

[mmmmmmmmmmmmmmmmmmmdonuts]

I'll close this. I just tried it on Fedora 42 with the wayland session and it seemed to open just fine.
