If you drag an image or any file from Dolphin to another window − this window stops responding to the mouse cursor (clicking, hovering, does not respond to the mouse at all). The keyboard shortcuts work and you can exit or do something without the mouse. In 100% of cases, the bug appears if you drag a Dolphin image or any file to Chromium. The problem appeared around the beginning of February 2024. I thought this would no longer be the case in Plasma 6, but unfortunately the bug has persisted. chrome://flags/ −> Preferred Ozone platform <Wayland>.

Does this only happen when you drag to Chromium, or to other windows too? If so, which other windows? If it's just Chromium, what happens if you run it in XWayland move rather than forcing it to native Wayland mode?
If I switch Chromium to x11, then dragging files works and the mouse works fine. chrome://flags/ −> Preferred Ozone platform <x11>. But then there are a lot of other problems. Everything works more stable in Preferred Ozone platform <Wayland>. The problem is only with dragging files, I'll describe it in more detail below. I'm attaching a video. If I drag absolutely any file into the browser window, it does not respond to the mouse. If you then drag any file into the browser window and wait for it to react to it, BUT do not release this file, but return it back to Dolphin, then Chromium works fine again and reacts to the mouse. But if you drag the file to Chromium again, the problem repeats. You need to drag any file to Chromium again, hold it over the window, but do not release the left mouse button and return it back to Dolphin. And so it is every time I transfer any file to Chromium. This problem occurs only in Chromium and in 100% of cases.

The video shows that the cursor freezes, but nothing freezes. It also moves smoothly, it's just that Chromium doesn't react to it. I was recording a video in Spectacle. Please add the ability to customize video recording settings to Spectacle. Otherwise, it sets the settings automatically and the frame rate drops very much (it is dynamic) if I move only the mouse.
Thanks. This is either a problem with Chromium's native Wayland mode, or a problem in KWin's. I'll let the KWin developers determine from here which one it is.
Created attachment 169109 [details] Similar bug on my arch linux KDE I would like to input on this I have a similar bug but it's triggered differently, when I select any portion of text and drop it inside chrome the mouse gets stuck and I can't click anything anymore until I kill chrome, this happens only on KDE I tried the same thing on Gnome with Wayland enabled and it doesn't happen. Steps to reproduce the problem 1/ start chromium with -enable-features=UseOzonePlatform -ozone-platform=wayland 2/ Go to any webpage (eg. wikipedia) 3/ select any chunk of text using the cursor 4/ Drag the text inside and drop it anywhere inside chromium My Setup: System: Kernel: 6.8.8-2-cachyos arch: x86_64 bits: 64 Desktop: KDE Plasma v: 6.0.4 tk: Qt v: 6.7.0 wm: kwin_wayland vt: 1 dm: SDDM Distro: CachyOS base: Arch Linux GPU: Graphics: Device-1: Intel Alder Lake-P GT2 [Iris Xe Graphics] vendor: Lenovo driver: i915 v: kernel arch: Gen-12.2 ports: active: eDP-1 empty: DP-1,DP-2 Device-2: NVIDIA GA106M [GeForce RTX 3060 Mobile / Max-Q] vendor: Lenovo driver: nvidia v: 550.78 arch: Ampere pcie: speed: 2.5 GT/s lanes: 8 ports: Monitor-1: HDMI-A-1 pos: right res: 1920x1080 size: N/A modes: N/A Monitor-2: eDP-1 pos: primary,left res: 2560x1600 size: N/A modes: N/A
And to answer Nate question, In my case when you drag text from chrome to other applications windows or to other chrome tabs or from outside chrome ti chrome nothing happens, the issue only triggers when you drag something (picture or text) from the same tab and you drop it in the same tab.
Same situation. Every time I accidentally drag, it freezes Linux Arch KDE6 (Wayland) Chrome stable Version 124.0.6367.118 (Official Build) (64-bit)
