Tested 17.3.3, no success. The artifacts appeared after the #1735594 fix, so they may be specific to i965. My computer graphics indicate "Mobile Intel® GM45 Express Chipset".
I found that the game titanion looks as expected when the window is resized to 960x720 or greater. Inspecting the source I found the game adjusts the line width at window resize while the other games keep it at 1 or 2, so I believe the driver is drawing the lines thinner than it should. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1752844 Title: Line drawing bug in applications using opengl 1 Status in mesa package in Ubuntu: Incomplete Bug description: On Ubuntu 16.04.3, as from the update fixing https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1735594, the line rendering in applications using Opengl 1 is incorrect.
