SUMMARY
The Night Light widget in Plasma 6.3.0 breaks some egl compatibilty in Wayland

STEPS TO REPRODUCE
1. Open System Settings → Appearance & Style → Colors & Themes → Night Light.
2. Check any option other than "Always Off"
3. Move the slider of the the Night Light temperature

OBSERVED RESULT
1. The screen goes totally black for at least2 seconds at each cursor slide
2. journalctil shows these lines:
```
plasmashell[6552]: qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface: 0x655483ccdb80
kwin_wayland[6386]: kwin_scene_opengl: 0x505: GL_OUT_OF_MEMORY error generated. Failed to allocate memory for texture.
kwin_wayland[6386]: kwin_scene_opengl: Invalid framebuffer status:  "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"
...

EXPECTED RESULT
The color temperature preview should work as expected, not crash!

ADDITIONAL INFORMATION

Another closely related consequence of this is that if you have Night Light mode active and you boot with Plasma 6.3 on Wayland during the “night color time”, then you won’t be able to start the desktop at all! You can fix this by disabling NightColor inside ~/.config/kwinrc:
```
[NightColor]
Active=false
```

and then you can log in again.
