annoying bug quartus @ Xubuntu

Are you trying to run Quartus on an unsupported operating system?

Xubuntu does not seem to be supported. While you can try to install Quartus on an unsupported OS, please note that you will do so at your own risk and no technical support will be provided.

Please refer to the supported OS list here:

https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-software/os-support.html#tab-blade-1-1

I recommend running Quartus on a virtual machine with a supported OS to check if the issue is caused by the unsupported OS.

Additionally, you might want to try the following solution to see if it scaling/display issue:
