[db47h]

Description

In NewWindow, set options.Linux.WebviewGpuPolicy to WebviewGpuPolicyNever if options.Linux is nil, disabling GPU acceleration by default on linux until the upstream bugs https://bugs.webkit.org/show_bug.cgi?id=228268 and https://bugs.webkit.org/show_bug.cgi?id=261874 are fixed.

Type of change

@db47h Please could you add an entry to the changelog located at website/src/pages/changelog.mdx?

[db47h]

@leaanthony sure, sorry I forgot about that. Should I submit a new PR just for this?

I just tried this on my linux box that was demonstrating the same problem:

$ go install github.com/wailsapp/wails/v2/cmd/wails@master
go: downloading github.com/wailsapp/wails v3.0.0-alpha.0.0.20231106094614-57c04ba740ae+incompatible
go: downloading github.com/wailsapp/wails/v2 v2.6.1-0.20231106094614-57c04ba740ae
...
$ wails version
v2.6.0

and still have the same issue:

$ ./build/bin/myproject 
Overriding existing handler for signal 10. Set JSC_SIGNAL_FOR_GC if you want WebKit to use a different signal

(WebKitWebProcess:3668532): Gdk-ERROR **: 10:57:13.052: The program 'WebKitWebProcess' 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 203 error_code 2 request_code 152 (GLX) minor_code 34)
  (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.)

Am I doing something wrong?

[db47h]

@gmlewis please open a new issue for this. Although what you are experiencing does not look related, I may very well have broken something and this needs some investigation. In the new issue please report tests with an earlier version (like commit 0a63215), with and without setting WEBKIT_DISABLE_DMABUF_RENDERER=1. Please also mention this PR in the new issue so that I get a notification.
