[Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

As the title says, kitty terminal no longer has transparency after updating to plasma 6.0.2 (Wayland), was working fine in Plasma 5.27.10 (Wayland).

My kitty.conf:

> cat ~/.config/kitty/kitty.conf
background_opacity 0.8
background_tint 1
copy_on_select yes

map f1 launch --cwd=current
map f2 launch --cwd=current --type=tab
map ctrl+shift+. move_tab_forward
map ctrl+shift+, move_tab_backward

background tint 0 or 1 has had no impact

Plasma, kwin, ...: 

> pacman -Qii plasma-desktop 
Name            : plasma-desktop
Version         : 6.0.2-4
Description     : KDE Plasma Desktop

GRUB_CMDLINE_LINUX=""

fbdev had no influence on transparency

Nothing showing up in journalctl when I launch kitty other than 

systemd[954]: Started kitty - Terminal emulator.

Any leads on fixing the transparency without having to create a Plasma "Window Rules" would be appreciated.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Does it still work in plasma/X11 and does kitty there show up as ARGB/32bit in xwininfo?

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Hi Seth,
Thanks for the reply.

Transparency of kitty terminal as configured from kitty.conf does indeed work on plasma6/x11.

Kitty terminal in x11:

xwininfo: Window id: 0x740000b "xwininfo ~"

  Absolute upper-left X:  480
  Absolute upper-left Y:  28
  Relative upper-left X:  0
  Relative upper-left Y:  0
  Width: 891
  Height: 1052
  Depth: 32
  Visual: 0x7e
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x740000a (not installed)
  Bit Gravity State: ForgetGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no
  Map State: IsViewable
  Override Redirect State: no
  Corners:  +480+28  -2469+28  -2469-0  +480-0
  -geometry 891x1052+480-0

Naturally, xwininfo does not work when in Wayland (transparency too).
I'm not sure what this ARGB is referring to.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

"alpha red green blue"

https://github.com/kovidgoyal/kitty/issues/7202 - do you set linux_display_server? Does "kitty --linux_display_server wayland" work as expected?

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Sorry I did not specify my version of Kitty

pacman -Qii kitty
Name            : kitty
Version         : 0.33.0-1

It is not kitty-git.
From wayland,

> kitty --linux_display_server wayland
Unknown option: --linux_display_server

Placing as an option in kitty.conf does nothing either.

Following the linked issue:

 > kitty --debug-rendering

Tracing further from the linked issue in the Kitty repo leads to https://github.com/NVIDIA/egl-wayland/issues/85, which might be part of the problem? KDE monitors are currently not set to HDR because SDR ends up having very washed colours.

OpenGL relevant...

I can't tell if the OpenGL version being 3.1 is just a Nvidia-driver thing.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Sorry, applied alacritty logic and also probably misunderstood the last post, they're forcing xwayland.

kitty -o linux_display_server=x11

But that's not a great solution and the GL mis-version and missing dri2 screen is kinda shady.
Do you enable https://wiki.archlinux.org/title/NVIDIA … de_setting - using the "nvidia_drm.modeset=1" kernel parameter (modprobe.conf won't remove the simpledrm device)

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Hi Seth,
Thanks so much for the support so far

kitty -o linux_display_server=x11

does has transparency just as it has had on X11 indeed.
Besides my kernel params I've posted above, I also have: 

cat /etc/modprobe.d/nvidia_drm.conf
options nvidia_drm modeset=1
options nvidia_drm fbdev=1

on this whole time... which might have made the fbdev grub parameter redundant hm....
For completion 

ls /etc/modprobe.d/

2 mins later...
Removing fbdev=1 and rebooting from both modprobe.d/nvidia_drm.conf and kernel params haven't amounted to resolving the transparency either.

I'll just chalk this up to being an outdated OpenGL issue then.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Same behavior on weston?

OpenGL version string: 3.1.0 NVIDIA 550.54.14
OpenGL platform interface: EGL
OpenGL shading language version string: 1.40 NVIDIA via Cg compiler
Driver: NVIDIA
Driver version: 550.54.14
GPU class: Unknown
OpenGL version: 3.1

The GL 3.1 nonsense certainly is also part of the compositor - your GPU or the GL implementation in the driver isn't too old™, it does 4.6, the newest possible iteration.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Is this a GPU driver problem or a Kwin problem? I could file a bug report with the Kwin people if it is so, I still barely comprehend the source of the GL 3.1. (I'm assuming its just Nvidia.) I might do a laptop backup and update my laptop to Plasma 6.0 just to compare it with an AMD gpu system in a while.

With regards to Weston, do you wish for me to try on Weston too (I'm guessing I'll have to install Sway or something...? Hoping my ~ doesn't get too scuffed after.)

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

You can just try weston (it's the reference wayland compositor, no need to install sway or anything)
eglinfo says that the nvidia driver correctly reports OpenGL 4.6 - I could imagine that this comes out of kwin to provide some minimum version or so.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

I've installed weston and launched from under Plasma6/Wayland and a TTY, followed by trying to launch Kitty from the Weston-Terminal. Result: 

[destroyed object]: error 7: importing the supplied dmabufs failed
[078 blah blah timestamp] [glfw error 65544]: Wayland: fatal display error: Protocol error

kitty with linux_display_server=x11, with weston from kitty in Plasma6/wayland:

[078 blah blah timestamp] The output buffer does not support sRGB color encoding, colors will be incorrect.

But the transparency is fine as established.

kitty with linux_display_server=x11, with weston from tty: 

[glfw error 65544]: X11: The DISPLAY environment variable is missing

I'm not sure if I should be setting to :0 or display-0 (or 1 instead of 0).

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Quick google of "kwin minimal openGL version", found this reddit post rip?
Also updating the post title...

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

The reddit post isn't relevant to this.
Apparently the "GL version string" indicates 3.1 regardless of the compositor (except maybe gnome)

Oooh surprising... Kinda weird but sure that kitty --debug-* would have been inaccurate (probably just pulling from eglinfo?)

yeah that was the chain of issues that led me to the egl-wayland nvidia thing too
guess it really is just an Nvidia issue then! neutral

thank for the help still Seth!

edit: https://github.com/NVIDIA/egl-wayland/i … 1930675281 clearly did not make it into r550 since I'm having this issue??

For what it's worth, I have a similar setup, with the same issues regarding kitty transparency after the update.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

Welcome RoboBlaster to the forums!
FWIW, I guess the only solution now on Plasma6/Wayland is

> head ~/.config/kitty/kitty.conf -n 1
linux_display_server x11

till nvidia/egl-wayland fixes the issue. I'll try replicate on an AMD gpu before I mark the thread as solved.

Hi - thanks! Good to know it's a matter of an update rather than a screwy config.

Re: [Solved]Transparency of Kitty0.33 and Kwin under Plasma6.0 with Nvidia

It's not a given that this will fix it and even if, the mitigation(?) in kitty might still prevent the impact: https://github.com/kovidgoyal/kitty/iss … 1982353024
But yeah, this heavily looks like nvidia vs. wayland vs. kitty, not an EBKAC - at least not your chairs wink

Finally did a full upgrade on my AMD machine, kitty terminal has no issue on it. Marking this thread as solved.
