map shows incorrectly with WSL2 on RX6600

[One2INF]

I follow this article to setup my wsl2+ros environment. But the map shows incorrectly. It seems only half of map shows.

• The same package works well in vmware+ubuntu.
• I test it with another computer(AMD Ryzen 7 5700G with Core Graphics card). The problem happen again.

Your environment

• OS Version: Windows 11 Pro 21H2 (22000.832) running WSL2 with Ubuntu 20.04
• ROS Distro: Noetic
• RViz, Qt, OGRE, OpenGl version as printed by rviz.

I solved it by export LIBGL_ALWAYS_SOFTWARE=true as mentioned in ##1748. I will verify it in another computer.

Good that the work-around using software rendering helped you. However, please also upvote (:+1:) the upstream issue https://github.com/microsoft/wslg/issues/744. Thanks.
