Menus in Plasma 6 are too big

[evgeniy-harchenko]

The menus are too big when they appear for the first time. When they are opened the next time, their size is normal. After restart app menus are big again. Tested on KDE Neon 6 (X11).

Example (video)

It should be about a bug in that app (Dolphin?). Have you seen it in a non-KDE Qt6 app — or in any other app?

[evgeniy-harchenko]

I checked a lot of KDE apps, they all have this issue, even plasmashell (desktop context menu). There is no issue in other non qt6 apps e.g. doublecmd-qt, transmission-qt. A little bit later I'll check non-KDE Qt6 apps.

To see the problem firsthand, I have to wait until Plasma6 comes to my distro — it will soon.

A little bit later I'll check non-KDE Qt6 apps.

No need to that. I already have many Qt6 apps, and none of them shows this symptom.

Oh, another question: Do you have the latest git Kvantum?

[evgeniy-harchenko]

Yes, I have the latest git version. But I decided to reinstall it, for the first time without any success. Then I manually removed all files and installed again. Now it works as expected. So most likely the problem is on my side. Closing.

Qt 6.6 had a regression, for which I had included a workaround in git Kvantum. That's why I asked about git Kvantum.

Anyway, whenever Plasma6 comes here, I'll check its menus.

Thanks for reporting.

[tsujan]

Let's reopen this until Plasma6 comes here....

[FGD-Garuda]

What is the workaround?

I am running git 1.0.10.r52.ge1c4d44a-1

There are lot of changes (and bugs) in the new Plasma 6, I know that. 😄

Thanks for still maintaining kvantum!

Thanks for still maintaining kvantum!

You're welcome! Kvantum will be developed indefinitely.

As for Dolphin's regression in its status-bar (#951 and #955), see #951 (comment)

[evgeniy-harchenko]

@FGD-Garuda as a temporary fix you can edit *.kvconfig file of your theme. Reduce value of layout_margin in [%General] section. E.g. set it to 5.

P.S. Many thanks @tsujan for Kvantum!

Hi!
Reducing that value to 4 on the Sweet theme specifically made it work perfect. I did not see a downside effect to that, meaning I didn't notice anything breaking somewhere else.

Other themes will require a smaller increment reduction because the area was already less cut off.

Tnx!

[tsujan]

This new piece of info might be useful to Dolphin's devs for fixing the regression because layout_margin sets PM_LayoutLeftMargin, PM_LayoutRightMargin, PM_LayoutTopMargin and PM_LayoutBottomMargin.

@evgeniy-harchenko, thanks for finding it; @FGD-Garuda, thanks for confirming it!

However, I'm not sure that the problem will be completely fixed if they consider those QStyle parameters in their codes.

I report my experience on archlinux. Before, there was no way to glue correctly even on Dolphin, see video https://youtu.be/tQ98eETr_2Y

Installed via yay -S kvantum-qt6-git and the problem was resolved immediately.

In fact, with dual monitors it reported that the drop-down menu was not displayed.

Yes, that's a multi-screen bug in Qt 6.6, for which I included a workaround in git several months ago:

Kvantum/Kvantum/style/eventFiltering.cpp

Lines 1274 to 1279 in 2284b56

	#if (QT_VERSION >= QT_VERSION_CHECK(6,6,0))
	/* WARNING: Because of a bug in Qt 6.6, translucent menus -- especially context menus
	-- may be drawn with their minimum sizes and without contents after being
	moved on a non-primary screen. As a workaround, the menu is resized here. */
	w->resize(g.size());
	#endif

The workaround will be in the next release.

Had the same problem, but it seems that the problem was gone when I switch to using kvantum-git as suggested, at lease not so easy to repeat the problem, tried many times and it is ok. And thanks for maintaining this project, it is awsome!

@luxl
Thanks for confirming that the menu problem is fixed in git!

[tsujan]

I tested menus of Plasma 6.0.2 with Kvantum 1.1.0 (released an hour ago) and couldn't find a problem. Closing....
