gl4es BadWindow error with some apps

Hello! I run gl4es on top of swiftshader libraries. Apps like Chocolate Doom, xfce4 works fine, but glxgears, glxinfo, vivaldi browser and maybe other apps dont work. gl4es shows me BadWindow error in log.

As Xorg server i tried to use VcXsrv, android Xsdl and Xvfb.

$ glxinfo

Are you sure ChocolateDoom and xfce4 use opengl? I think fo now gl4es doesn't work for you on all apps.

I need more logs, please uncomment line 36 of src/glx/glx.c to have more details on the interaction with X Server.

I see EGL is working because gl4es can check some hardware capabilities. I think you can have some stuffs on screen using LIBGL_FB=3 export (but it may be a bit slow). Try also with LIBGL_FB=1 to have fullscreen (using Xvfb I guess).

I sure xfce4 and ChocolateDoom use opengl(i see in command output log of gl4es).

Can i close this issue or you will answer?

Jan 09 '19 07:01 zhenyolka

If it's still not working, don't close the issue.

I'm still unsure why it doesn't want to create that context. I need to think about it. I'll put a comment here when I have a new code to test.
