[SOLVED - Bug] KDE Menu's get stuck when in full screen an application

Hi, I'm hoping this is my last issue now that I have moved to Arch (from Ubuntu).

I'm using KDE 5 Plasma as my desktop, for the most part it's working great. On login it tells me some part of KDE died and needed to restart, but it doesn't break anything for me (just shows an error briefly).

My exact issue is a little hard to describe, so let me explain my setup first. I have 2 screens, a BenQ monitor as my main screen (where the KDE menu bar is with open apps, system tray and the clock etc) and a TV.

Now if I open a video for example (in VLC or MPV) everything is fine. I then make the video full screen on the TV so I can still see the menus and that's where they freeze up.

At the time of writing it is 22:41 on the clock, now if I enter full screen the menu reverts to showing 21:36 and the list of apps open matches what was open at that time.

The menu still works underneath, but it doesn't show mouse over or what have you. But is functional and I obviously can't tell what I am clicking on.

A hard problem to google but fortunately not a huge problem. How can I debug, has anyone had this issue before?

I'm using SDDM to login and it's X rather than Wayland (though I haven't been able to successfully login with Wayland)

Nobody else having this issue? Just me?

Don't bump your posts: https://wiki.archlinux.org/index.php/Co … ct#Bumping

What's your graphics adapter? Presumably KWins OpenGL Compositor crashes, do you get any info in

dmesg

while this issue occurs? A quick fix would be restarting kwin by issuing

kwin_x11 --replace &

from a terminal or I often like to use KRunner (alt+f2) for this.

Sorry for the bump. I for the first time this morning could not reproduce the error, typical!

But I just did, so now I feel it's a certain combination of apps, or one app in particular. The kwin_x11 --replace & fixed the issue and gave me something to play with. It did show some errors but nothing that sounded too scary (example):

QXcbConnection: XCB error: 9 (BadDrawable), sequence: 2339, resource id: 0, major code: 14 (GetGeometry), minor code: 0
and
QXcbConnection: XCB error: 3 (BadWindow), sequence: 18175, resource id: 117440516, major code: 18 (ChangeProperty), minor code: 0

I will experiment and post my findings.

There's a known issue with certain OpenGL windows on the nvidia driver and KWin. Apparently nvidia has identified and fixed the issue in the nvidia-390xx branch of the driver. For the non 390xx driver we will likely have to wait for the next feature release, as 396 isn't slated for another minor update.

Re: [SOLVED - Bug] KDE Menu's get stuck when in full screen an application

Good to know, but my version is newer so should include that particular fix:

OpenGL vendor string:                   NVIDIA Corporation
OpenGL renderer string:                 GeForce GTX 770/PCIe/SSE2
OpenGL version string:                  4.6.0 NVIDIA 396.24
OpenGL shading language version string: 4.60 NVIDIA
Driver:                                 NVIDIA
Driver version:                         396.24
GPU class:                              Unknown
OpenGL version:                         4.6
GLSL version:                           4.60
X server version:                       1.20
Linux kernel version:                   4.17.2

Fortunately this isn't a show stopper. But would like to get everything perfect. My OCD demands it!

That version is not newer (in terms of release date), 390xx has received a new release (390.67) (it is an LTS version that will continouously receive "minor" version bumps containing bugfixes), containing said fix, which is still missing from the short lived 396 branch.

Oh I see, so this is just a minor known bug then. I didn't know there were long and short term branches. I'll stick with bleeding edge for now. Thanks.
