Same problem here: Dell Latitude E6540 with Intel HD4000 + AMD Radeon HD8790M (OLAND), Ubuntu 16.04 updated. Some OpenGL programs do not refresh the windows and shows only artifacts from background when using DRI_PRIME=1 to lunch (e.g. with kicad pcbnew)
Followed comment #11 suggestion and tried latest Oibaf PPA ( https://launchpad.net/~oibaf/+archive/ubuntu/graphics- drivers?field.series_filter=xenial ) with: - mesa 12.1~git1608230730.96ea75~gd~x - xserver-xorg-video-ati 1:7.7.99+git1608230731.b08670~gd~x - xserver-xorg-video-intel 2:2.99.917+git1608121931.c8fc7f~gd~x - libdrm 2.4.70+git1608210630.b214b0~gd~x - llvm-toolchain-3.9 1:3.9~+rc2-1~exp1~gd~x with same result, so updating to mesa 12.1 seems does not solve the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1430888 Title: DRI_PRIME with radeon/intel windows do not draw To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1430888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
