Huge problem with IDE Flickering (Arduino is unusable)

[hugo_maker]

Hi,
I'm new to the forum but I've been using arduino since 9 years.
I'm experiencing the biggest issue I've ever had with this 2.3.4 IDE. It flickers like anything else and make the software unusable.
Here is a video I filmed that shows the problem : https://youtu.be/6ZOEZsYoYlM?si=OMf6PaGCARLHqBNZ
This is the ONLY software that does this, I have a fresh win 11 install.
Nvidia 3060 Ti drivers up to date.
Win 11 up to date as well

I tried to uninstall and reinstall back again, tried CCleaner but there is no visible solution to this. How is that possible ? I need help and a functionnal IDE please.
Thanks. Hugo

Hi @hugo_maker. Try this:

1. Select File > Quit from the Arduino IDE menus if it is running.
   All Arduino IDE windows will close.
2. Start Windows "File Explorer".
3. Open the Arduino IDE installation folder.
   ⓘ The default installation location is at one of the following paths:

   • C:\Program Files\Arduino IDE
     

   • C:\Users\<username>\AppData\Local\Programs\Arduino IDE
     

     (where <username> is your Windows username)
     If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
4. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
   A context menu will open.
5. Select "Open PowerShell window here" from the menu.
   Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
6. Type the following command:

   & ".\Arduino IDE" --disable-gpu
   

7. Press the Enter key.
8. Wait for Arduino IDE to finish starting.

Now check to see if the flickering problem still occurs. If not, then starting Arduino IDE with the --disable-gpu flag will be an effective workaround. You can configure the shortcut you use to start Arduino IDE to use this flag to make it more convenient. I can provide instructions for doing that if we determine that it will be useful.
