Manjaro KDE : Konsole and some applications which based on KDE display problems

Like this. Not only konsole has this bug,but krita has it too.
I have tried many solutions, such as renewing my video drivers, using non-free drivers, but it's all useless.
Other applications are normal,such as settings,vscode,vmware and so on.
My computer is GIGABYTE AERO 15 Classic XA ,i7-9750H,NVIDIA GeForce RTX2070 with MAX-Q Design.

Isn't that theme thingy?

Yeah , I have tried all the themes inside in KDE.
I also closed all window effects,but it is useless .

Change your compositor to opengl 3.1 and see if that fixes it.

System Settings -> Display and Monitor -> look on the right and you'll see Rendering Backend, use the drop down and select OpenGL 3.1. -> click Apply.

Thank you for your solution but it is useless either.
Another weird thing is ,when I want to print screen, it will disappear,so only can I use my phone to take a photo.

Since its laptop are you using
Optimus manager or optimus switch to use nvidia??


No,I haven't used it before.

Then you are on bumblebee so you won't get to use nvidia to its potential

I am sorry to disturb you, but the problem comes back again..

I have reinstalled bumblebee and potimus-manager, and I haven't upgraded the kernel recently.

when I firstly noticed the problem coming again, I have run $ oprirun ,
and it shows:
[ 45.102151] [ERROR]The Bumblebee daemon has not been started yet or th
e socket path /var/run/bumblebee.socket was incorrect.
[ 45.102232] [ERROR]Could not connect to bumblebee daemon - is it running?
Then I reinstalled the software and checked my drivers.
and run $ systemctl enable bumblebeed
and reboot serval times,
but the bug exists anyway!

Recently I renewed my disk partition on Windows and grub has been broken, linux partition has changed its ID, but I fixed it. Is this something related to this thing?

I use the optirun to run Krita,and I recieved this:

If using optimus manager
Install optimus-manager-qt
Disable bumblebee.

I get this as well on my computer.
I think it might be the nvidia driver itself and how it's working with Plasma or how Plasma handles transparency maybe?
I haven't found any kind of fix for it. It wasn't doing it before on my machine with the previous nvidia driver.

I disabled bumblebee and it couldn't poweron now ...... I have reinstalled Manjaro linux.

I know how to solve this problem !
Disable your window zoom setting and all problems dissappeared .
But we can just set the font size to adapt screen.

Glad you found a fix. Unfortunately, it doesn't work for me. :frowning:

I'm pretty convinced it's, in my case, the propietary nonsense from nvidia. I have two systems running the exact same Manjaro KDE. One has nvidia graphics, the other AMD.

Actually, I do have a fix. As soon as the AMD 5700 XTs come out from AIBs with better coolers (Not that stupid blower) I'll get one of those. Problem solved for me. :wink:
