Created attachment 141472 [details] Firefox context menu small and with scroll arrow SUMMARY I file this bug as i was told here: https://bugzilla.mozilla.org/show_bug.cgi?id=1727072#c18 that the issue depends on the compositor and it can't be fixed from Mozilla side. In Firefox when i right-click the context menus frequently appear like this.
Created attachment 141473 [details] Firefox context menu correctly shown - whole size no scroll arrow The above comment and this one happen when you click towards the bottom of the viewport with little space below it for the context menu to appear. So the above issue happens but also sometimes the context menu is correctly shown in its whole size on top of/above the cursor - without any scroll arrow.
Created attachment 141474 [details] Context menu a little larger but still with scroll arrow This last case is what happens when i click somewhere close to the top of the viewport - it shows the scrollbar even then, so maybe what the issue is/what happens is an erratic behavior between two ways of working - one which tries to position the context menu inside the viewport and therefore generates scroll arrow; and another one, which doesn't care about the viewport and if it happens it also draws part of the context menu over the address bar so that it doesn't produce a scroll arrow. This is all speculation from myself.
Firefox Nightly and Firefox 92 Stable can reproduce this issue, but please test in Nightly as it has a lot of Wayland-related changes and i believe that the issue is exacerbated there. If Firefox Nightly is extracted in /opt/firefox/ for example you should run Nightly with the following commands: export MOZ_ENABLE_WAYLAND=1 /opt/firefox/firefox

Clicking the right-mouse button multiple times with fast/high frequency still reproduces the issue as does clicking with slow/low frequency. What i've found is that the issue in fact happens when you click not really close to the bottom of the viewport, but a little below the center of the viewport.
Created attachment 141511 [details] Display scaled
I cannot reproduce the issue. Can you please run firefox with WAYLAND_DEBUG=1 and post the output here? If possible, please reproduce the issue and close firefox as fast as you can so wayland debug log doesn't get huge and it's easier to parse it.
Created attachment 141538 [details] wayland_debug.txt In this log i reproduced it twice, that is, opened and closed the context menu two times one after the other. Both times it reproduces. The log is still big but i guess it should be somewhere close to the end. I hope it would help you.
Also cannot reproduce when using current git master packages and Firefox in native Wayland mode.

[3012861,376] xdg_popup@72.configure(981, 463, 351, 353) [3012861,553] xdg_surface@71.configure(404) it looks like firefox specifies the following constraints: slide_x, flip_x, flip_y, resize_x, and resize_y. based on the configure event, kwin has resized the popup for some reason instead of flipping it vertically. there were some improvements with geometry updates in 5.23. maybe this bug got fixed without us realizing it.
I suspect so. The Firefox 92 update also fixed a lot of wayland-related glitches with menus for me. Please re-open if you can still reproduce the issue with Firefox 92 in Plasma 5.23. Thanks!
I can still reproduce with Firefox 93.0 and Plasma 5.23.
Can you please post WAYLAND_DEBUG output again but now when the popup is not resized? On a second look, the popup contains a lot of entries and (In reply to Vlad Zahorodnii from comment #12) > it looks like firefox specifies the following constraints: slide_x, flip_x, > flip_y, resize_x, and resize_y. bothers me. If the popup is too big and `slide_y` is absent, kwin may have no choice but resize the popup. `slide_y` indicates whether it's fine to move the popup up or down if parts of it lie outside the screen.
Created attachment 142492 [details] Firefox context menu WAYLAND debug log I guess "when the popup is not resized" means when it doesn't have that glitch, that is, when the context menu is shown in full size and not cropped with scrollbar. Here is the log.
[1498720,978] -> xdg_wm_base@24.create_positioner(new id xdg_positioner@75) [1498720,996] -> xdg_positioner@75.set_size(351, 659) [1498721,014] -> xdg_positioner@75.set_anchor_rect(1033, 189, 4, 4) [1498721,039] -> xdg_positioner@75.set_offset(0, 0) [1498721,056] -> xdg_positioner@75.set_anchor(8) [1498721,068] -> xdg_positioner@75.set_gravity(8) [1498721,080] -> xdg_positioner@75.set_constraint_adjustment(61) [1498721,092] -> xdg_wm_base@24.get_xdg_surface(new id xdg_surface@76, wl_surface@65) [1498721,114] -> xdg_surface@76.get_popup(new id xdg_popup@77, xdg_surface@52, xdg_positioner@75) [1498721,139] -> xdg_positioner@75.destroy() [1498721,150] -> wl_surface@65.commit() ... [1498747,316] xdg_popup@77.configure(1037, 193, 351, 659) Okay, assuming that the anchor rect somewhere in the top half of the screen, this all makes sense. Can you please file a bug report to firefox developers asking to add SLIDE_Y xdg-positioner constraint adjustment (or re-open https://bugzilla.mozilla.org/show_bug.cgi?id=1729944)? As is, I'm afraid kwin is doing the right thing. If the popup can't be flipped vertically, the only thing that kwin is allowed to do is resize the popup.
