Menu bar and icon options text missing in Archlinux LXQt

Arduino 1.8.13 (using your Software Download) was working ok until I did an Arch system upgrade. See screenshot below. The options are there, but not visible. If I click on "Open", for example, and blindly follow down and click on something - a sketch will open.

I did a system downgrade (rollback) using the Arch Archive to the previous upgrade date, and the IDE worked correctly again. I don't know which package(s) caused the problem as there were 124 packages upgraded after a 3-week interval (remiss of me). So, I brought my system back up-to-date and tried something else:

In the IDE download folder there is a folder named 'java'. I renamed it to something different and launched the IDE - everything working ok. **This is my solution for now.**

Being curious, I also installed the Arch Arduino 1:1.8.13-2 package using pacman package manager . I note that the 'arduino' folder /usr/share/arduino does not contain a folder 'java'. I prefer to use your Arduino Software, so I will stay with that.

I have another machine running Archlinux, it behaved the same way as above.

You may not consider this to be an arduino.cc issue, but I just wanted to make you aware.

OS: Archlinux 64-bit
Desktop: LXQt
Java Environment: java-14-openjdk


Start by reproducing the missing menu and icon text in the Arduino 1.8.13 IDE on Arch Linux with LXQt and java-14-openjdk. Compare the behavior with the downloaded IDE's bundled java folder renamed and with the Arch package; done means the options render normally without that workaround.
