aegisub no more working after update...

[François Patte]

Bonjour,

I just update my system (fc-32) and aegisub is no more working: I can 
open subtitlefiles but not the corresponding video...

Here the message:

(aegisub:347417): Gdk-ERROR **: 12:08:25.195: The program 'aegisub' 
received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
   (Details: serial 37349 error_code 2 request_code 150 (GLX) minor_code 24)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the GDK_SYNCHRONIZE environment
    variable to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() 
function.)

I don't understand what it means and don't know what to do....

Thank you for any help.
