Last modified: 2016-10-16 07:43:11 UTC
Created attachment 337743 [details] lsmod, lspci and installed packages When I start epiphany 3.22.1 under wayland there are a lot of video glitches that make impossible to see the window content. Using the flag GDK_BACKEND=x11 that bug do not happens. That bug is happen on a desktop with a radeon rx 480 with fully update open source stack, mesa, amdgpu and kernel 4.8. It not happens on a notebook ivybridge with intel video driver. I'm using fully updated Arch Linux. There isn't backtrace on gdb. To reproduce: 1 - open epiphany on gnome 3.22 wayland on amdgpu stack;
Thanks for taking the time to report this. This issue is most likely a bug in WebKit. Please report the bug to https://bugs.webkit.org/ including a link to this bug report and noting the version of WebKitGTK+ that you have installed. When reporting the WebKit bug, be sure to include the prefix '[GTK]' in the bug summary and select the 'WebKit Gtk' component.

But that bug affects all interface ingluding the gtk part, not just the "webview", is just webkitgtk?

No, it can also be GTK, try running with GDK_GL=disable (this will only work if you use 2.14.1, not 2.14.0). Also ensure you have t least GTK+ 3.22.1 that includes this fix: https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=7292b035593008e79cf4aae1b8dcf0f7a83bc55f
Using this flag (GDK_GL=disable) that problem just happens with the webview.

Um, so what do you think, Carlos? Should it be reported to amdgpu? It's not lost on me that WebKit seems to trigger this issue. Presumably Márcio would have filed this against GTK+ if other GTK+ apps were having this problem.

OK, then it's definitely not a WebKit issue....
