Created attachment 126026 [details] screen recording SUMMARY On Wayland the whole context menu is delayed in ~1s. STEPS TO REPRODUCE 1. load the following link with Firefox https://wallpaperaccess.com/full/112752.jpg 2. drag the loaded wallpaper and drop it on desktop 3. OBSERVED RESULT Plasma takes some milliseconds to draw the context menu entirely. Watch the attached screen recording please. EXPECTED RESULT Plasma should draw the whole context menu immediately after we release the mouse button. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.18.0 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1
So what's the problem here? The fact that the menu changes a moment after it first displays? The same thing happens on X11. I think what's going on is that it first displays the basic menu immediately, then it takes a moment to look at the contents of the URL to determine what to do with it, at which point it's able to display context-appropriate actions. Showing the menu with context-appropriate actions instantly therefore isn't possible because the URL needs to be examined first, which necessitates network activity that might be slow. On X11, the cursor changes to a busy cursor during this time. It should do that on X11 too. I recall a recent patch that might have fixed this recently; do you think you could test again with Neon unstable?

This report is about X11. Screen recording on Plasma Wayland is still impossible. As we can observe in attached video, no busy cursor appears when mouse button is released.

If you drag to the desktop, wait 1 or more seconds, and then release, you'll see the busy cursor and the menu. Same root cause as Bug 448867.
