Screen tearing near top of screen using iris driver on Broadwell laptop with 19.3-rc3
I have a Dell Latitude E7450 (with HD Graphics 5500) and if I use the new Iris driver with it, I get pretty severe screen tearing mostly near the top of the screen at all times. This seems to only happen when I use the Kwin compositing window manager, but is unaffected by the vsync settings thereof. (If I launch kwin using the i965 driver and then launch individual applications with Iris, I don't get any tearing.) If I use the i965 driver instead, there is no tearing. If I run the Iris driver on newer systems (Skylake), I don't get any tearing there either. I attached a video demonstrating the tearing, along with the output of "glxinfo". If there is any other data I can provide, please let me know. Thanks!
