Hi all,

I have installed FreeFem++ on Windows Subsystem for Linux on Windows 11.

Whenever I run FreeFem++ filename.edp, I always get the following error message:

X Error of failed request: BadShmSeg (invalid shared segment parameter)  
Major opcode of failed request: 130 (MIT-SHM)  
Minor opcode of failed request: 3 (X\_ShmPutImage)  
Segment id in failed request: 0x600005  
Serial number of failed request: 64  
Current serial number in output stream: 65  
Segmentation fault

Can anyone please help?

Thanks!
