Hello! I’m enjoying my time with Manjaro ARM on raspi 4B so far, but my vlc player failed to display normally. It looks like this:
Along with my other application which works in other arm OS on raspi 4B:
Looks like the pixels are showed, but on wrong spot.
Help plz. 
Try Haruna media player. It is much more modern than VLC.
This doesn’t solve my display problems QAQ. Good video player tho. Thanks.
This looks like the gpu configuration - possibly something you can configure in /boot/config.txt
I have never seen what is going on in your pictures. What is more concerning is I have never seen anyone post the pictures like you have. The second picture which you said “Along with my other application which works in other arm OS” looks more like a Desktop as I do not see any window dressings but can not image you are “I’m enjoying my time with Manjaro ARM on raspi 4B so far” with a Desktop looking like that but you never said what the program was. Have you made any changes to your config.txt?
The very first thing I would do is to get off the stable branch and move to the unstable branch. It is the only branch that has been maintained in a very log time.
sudo pacman-mirrors -aS unstable && sudo pacman -Syyu
Your system is so outdated that it is going to require some manual intervention when updating to unstable. Take care of the errors one by one.
I think you can fix vlc by changing the renderer in its output settings:

This will only work if the problem is related with video playback. If vlc always seems like the one in the picture, even when you are not playing anything, then i’d get a new hdmi cable 
I tried a fresh start by re-burn the img file from the manjaro.org using raspberry imager. Didn’t fix this.
The 2nd picture is the screen of my application. It has a basically white UI, when it blur, it looks like a Desktop. The app usually looks like this:
Thank u for the advise! I will try update my system.
By the way, I am having some trouble uploading pictures. The mods helped me to make it a summary, but I can’t figure it out help plz.
do not use pictures - use words - text
Those are hopelessly outdated - they are all from feb. 2023
Windows applications are unsupported on ARM
Can HDMI cables affect individual programs? My desktop and browser works fine, but I can’t even see the settings in VLC.
I will give another cable a try tho.

Please do not post screenshots … if you must use pictures - use an image hosting service and link to the image.
Ok, I will try the unstable brunch.
The app’s name is “clash for windows”, it has a linux version. QWQ
Ok! I will use links next time. Sorry for the trouble I caused
Oh my gosh, It works. After upgrade, VLC is fixed, it works as it should now. The default scale ratio is set to 105%, need to change it to make icon clear and sharp tho
Thank you!!
Just a note. If you want hardware acceleration, you need to switch to mpv and rpi-ffmpeg. There are posts on the forum for configuration options.
Thank u! I will check it out
