## Problem After updating to KDE Plasma 6.8.0, notification popups appear as blank or dark rectangles. The text becomes visible in the **same popup after approximately 35 seconds**. This affects: - `notify-send` notifications - Browser notifications - System notifications, including Wi-Fi changes Notification delivery appears to work; the problem seems to involve rendering or updating the popup. ## System - Distro: EndeavourOS - Plasma / KWin: 6.8.0 - Session: Wayland - Qt: 6.12.0 - GPU: Intel Iris Xe Graphics (Tiger Lake GT2) - Driver: `i915` - Mesa: 26.2.4-1 - Kernel: 7.2.10-arch1-1 - Laptop: Dell Vostro 15 3510, Intel Core i5-1135G7 ## Relevant logs KWin repeatedly reports: ```auto Failed to allocate a graphics buffer for a swapchain ``` It also logs: ```auto This plugin does not support setting window masks ``` Plasma logs: ```auto No QSGTexture provided from updateSampledImage(). This is wrong. ``` I also observed this notification layout warning: ```auto QGridLayoutEngine::addItem: Can't add Body_QMLTYPE_617 (id="bodyLabel") at cell (1, 0) because it's already taken by Summary_QMLTYPE_639 (id="summary") ``` I don’t know whether these messages are directly responsible for the notification issue. ## Troubleshooting - Updated the system and rebooted. - Changed the Global Theme and Plasma Style to Breeze; the issue persisted. - Temporarily tested the Qt Quick software rendering backend; no fix. - Temporarily tested a KWin overlay-related environment override; no fix, and it was reverted. - Tested disabling Blur; this did not resolve the problem, and the original effect setting was restored. - Confirmed `org.freedesktop.Notifications` is owned by `plasmashell`. - Confirmed `notify-send` exits successfully. - `pacman -Qkk plasma-workspace` reported zero altered files. ## Questions 1. Is this a known Plasma 6.8.0 / Qt 6.12.0 notification rendering issue on Wayland? 2. Could the repeated KWin swapchain allocation failures be related? 3. Is there a known workaround or existing bug report? I would prefer not to reset my Plasma configuration or reinstall packages without evidence that doing so would help. Video showing KDE Plasma notification popups rendering as blank, dark rectangles on EndeavourOS with Plasma 6.8.0, Wayland, and Intel Iris Xe graphics. The notification text is not visible when the popup first appears. The issue affects application and system notifications. ![kde_notification_bug](https://forum.endeavouros.com/uploads/default/original/3X/9/c/9c4005f93408f0eaee628789aa3168de4f4ca201.gif) Thanks! ---

This video, at least for me, doesn’t show anything. Just seems like everything is blurred except some buttons. If you did the blurring, you should try to show the issue you’re experiencing when not using personal or confidential files/apps. Anyway, as far as troubleshooting is concerned, please try creating another user login account to test if the issue persists. If it doesn’t, then at least you know it’s something in your settings. Also, please check for another update. This is Arch, updates come fast, and pretty much every day. An update might just fix it. ---

Same here. This is a KDE Plasma related problem. I’m on CachyOS. Screen record: [https://youtu.be/u0A-XQeKHnM](https://youtu.be/u0A-XQeKHnM) Exact same symptoms after updating to Plasma 6.8: - Notification popups appear as empty/blurry dark rectangles in the bottom-right corner - After roughly 20 seconds the content suddenly renders correctly in the same popup - With the Blur effect disabled, nothing is shown at all - With Blur enabled, only the blurred rectangle is visible until the content finally appears Relevant log while triggering a notification: ```auto plasmashell: No QSGTexture provided from updateSampledImage(). This is wrong. ``` (repeated several times) Tested with notify-send (had to raise the timeout so the popup stays long enough to see the content appear). Restarting plasmashell does not fix it. Looks like the notification window itself is not being rendered properly at first — only the blur effect around it. System info: ```auto System: Kernel: 7.2.11-1-cachyos arch: x86_64 Desktop: KDE Plasma v: 6.8.0 wm: kwin_wayland Distro: CachyOS base: Arch Linux CPU: AMD Ryzen 7 5800X3D (8-core) Graphics: Device-1: AMD Radeon RX 7900 XTX driver: amdgpu Display: wayland compositor: kwin_wayland Monitor-1: Samsung LS49AG95 res: 5120x1440 hz: 120 scale: 110% API: OpenGL v: 4.6 mesa v: 26.2.4-arch3.1 API: Vulkan v: 1.4.363 driver: mesa radv ``` ---

Welcome to the forum :enos_flag: :enos: You seem to have a different mesa version on your system than I have ```auto API: OpenGL v: 4.6 vendor: amd mesa v: 26.2.5-arch1.1 renderer: AMD Ryzen 5 7600 6-Core Processor (radeonsi raphael_mendocino ACO DRM 3.64 7.2.11-arch1-1) ``` And I don’t have the problem you describe, so maybe a update will help ? ---

Thanks for the suggestion! I just ran a full system update and rebooted. Mesa stayed at 26.2.4-arch3.1 on my side (CachyOS) — it didn’t pull the newer version you have. Unfortunately the issue is still present with the exact same symptoms (blank/blurry notification popup for ~20 seconds, then the content appears, plus the repeated No QSGTexture provided from updateSampledImage() warning). So at least in my case it doesn’t seem to be fixed by the currently available updates. I’ll keep an eye on further mesa/plasma updates though. ---

Well that is a shame, but I do know that Cachy OS tends to follow a bit of a different path than EOS does. ---

I think its a KDE related problem, I reported it on [https://bugs.kde.org/show\_bug.cgi?id=527478](https://bugs.kde.org/show_bug.cgi?id=527478), too. ---

Maybe it is KDE related and maybe it is not because the arch mesa package can be found in the extra repository, and if I am not mistaking your mesa package might be found in a Cachy specific repository. Hence the arch1-1 vs the arch3.1 at the end of the mesa package names. ---

**Fix: change the global animation speed in the system settings, save it and the bug is gone. You can change it back to the old value after that.** Its a bug in KDE and they are working on it now. ---

That explains a lot because I always disable all animations 😀
