https://bugs.freedesktop.org/show_bug.cgi?id=103946 --- Comment #4 from Emil Velikov --- Issue is far before anything called DRI comes to play. Some of the HW units dealing with acceleration fail to init, hence everything is rendered by the CPU and slow. Karol has posted a workaround [1] which seems mildly related. You can try it by rebuilding the kernel with the patch applied. [1] https://patchwork.freedesktop.org/patch/190668/ -- You are receiving this mail because: You are the assignee for the bug.
