Could this be a duplicate of #503458? I also have video glitches, on both an older (9 years?) Dell desktop and a Dell Latitude 5590 laptop. I believe both use an integrated Intel video system; the laptop, which I'm using now: Intel Corporation UHD Graphics 620 (rev 07) Both machines, I've only seen it on Plasma on Wayland; it does not occur on Plasma/X11, or on Gnome/Wayland. I don't see it a lot for most programs, but I can absolutely guarantee it to happen in KPatience/Freecell (and Klondike) after the third or fourth move. It tends to get worse as the game continues. Forcing the window to redraw by resizing it clears out the glitches temporarily, until the third or fourth next move. It's not just a KPat issue, but that's where I can consistently demonstrate it, and the only place I can think of at the moment that I can definitely see it. Operating System: Debian GNU/Linux 13 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.13.0 Qt Version: 6.8.2 Kernel Version: 6.12.32-amd64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8650U CPU @ 1.90GHz Memory: 15.5 GiB of RAM Graphics Processor: Intel® UHD Graphics 620 Manufacturer: Dell Inc. Product Name: Latitude 5590 Please 1. confirm whether or not this still happens for you on latest Plasma (6.4) 2. upload the video somewhere else, I can't view that 3. attach the output of drm_info and kscreen-doctor -o (In reply to Kent West from comment #2) > It's not just a KPat issue, but that's where I can consistently demonstrate > it, and the only place I can think of at the moment that I can definitely > see it. QPainter did have some glitches in KPat at some point, but it was fixed. You might just be on an older Qt version with the problem. I'm no longer having this issue when using the following versions: Linux distro: CachyOS KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 Graphics Platform: Wayland Kernel 6.12.50-2-cachyos-lts mesa version: 25.2.3-2 Nvidia drivers: linux-cachyos-lts-nvidia-open 6.12.50-2 linux-firmware-nvidia 1:20250917-2 nvidia-utils 580.95.05-2 opencl-nvidia 580.95.05-2 Cool |
