The right-click menus have scrollbars when they can easily expand on the screen, for example the right-click menu on Trash.

Steps to reproduce

Expected behaviour
There shouldn't be scrollbars and it should be expanded from the start.

Yet another gtk regression

XFCE devs had to face a similar issue with Thunar, or at least an issue caused by regressions in GTK3 too. Even if the regression is caused by changes in GTK3, they ended up patching Thunar to make it work as intended with GTK3 3.24.7+.

Linux Mint devs might have to do the same thing: patching Nemo even if it they didn't do anything wrong with Nemo so far.

@FrogMcRibbit what was fixed in Thunar is a different issue, the submenu for templates was broken because its items were loaded asynchronously, which worked very well until GTK 3.24.5. I didn't have the time to prepare a reproducer sample to report it upstream, so I decided to drop the async load.
I wasn't super clear at https://bugzilla.xfce.org/show_bug.cgi?id=15200#c21, people also noticed the unnecessary scrollbars on context menu, that's what I meant when I said Nemo is also affected.

I have this issue, too. But only in places view and not in list view or tree view. And if I right click a place several times then the context menu for that place is displayed correctly.
System: Arch Linux 64bit with openbox, compton

I have same issue

[dikonov]

Please, fix the bloody menus in any way possible!
This is the MOST annoying bug in Cinnamon and it that makes me sorely regret that I have updated Cinnamon and GTK.

Can you guys confirm that if you select the sidebar item first (left click) then right-click, the menu displays properly. It should also be correct if using the keyboard menu button (not all keyboards have anymore).

Thanks

[malio10AC]

Yes, after a left click (on that item) the right click menu works properly.

I'm here to add a +1 on this. I'm not sure if this is helpful, but I converted a screen recording to a GIF to show the behaviour.
