Display Issue on xfce

General Help
1

I don't know how I can explain this by words so I am sharing a video.https://drive.google.com/file/d/1QLaJM1_HUE6RhNEiU2BBS4_r6Ss_MAgq/view?usp=sharing

(You might only be able to see the problem if you are on full screen and also mute the audio if you don't want to hear wired click noises. Don't know why the screen recorder enabled my mic in-between)

Had trouble uploading a video here. I don't know if it is because the video is in the wrong file format or what. Okay I will get to the point. These things only appear when I am in xfce and on full-screen. It doesn't happen all the time. Only on certain times like when I press a button. Help, it is getting worse day by day :frowning:. I use Zorin 16 Core xfce. Thank you in advance.

Can you please supplement the video with a description of what to look for? I watched the video several times, but I cannot figure out what it is I am seeing. You created a button to demonstrate, giving a pop up each time you pressed the button.
What is the display issue?

Ahhh.... I did not check if people from other devices could see it. I watched the video from another laptop and there I couldn't see the issues either. Maybe screen recorders can't record the issue i'm facing. Just wait a sec I will record a video from a phone and post it here.

This is actually a helpful clue along the way, though.
If the monitor is displaying differently from what the screen recorder shows...

It is better to mute the audio here too :sweat_smile:
The video quality is bad so it will only show a portion of the actual problem I am facing but you will understand what it is. You see the the prompt window getting cut off, the line which cuts it off actually extend even longer and most of the time there will be a big white Z like shapes on the screen.

Settings > Appearance > Fonts tab

Is Enable anti-aliasing checked?

What is your DPI?
Are you using any Scaling?

For the first question, yes. For the second one, it's 96. For the third one, no i guess.

Ah, great you pitched in :slight_smile: @anon96359095.
I was trying to watch the video but something is blocking it and was unable to. If the GPU is Nvidia, I think you have some good idea.

To find out the GPU that you are using, please do the following commands.

Hold CTRL ALT t to enter terminal

sudo apt install inxi

Enter your password. Then type Y when it asks you to.

Once installed, please run the following command...

INXI-G

Please post the results. Here is my INXI-G for example...

The INXI-G command did not seem to work for some reason.
