When tooltips are shown in Chromium, their windows contain garbled and uninitialized pixels. No idea if that is relevant. I'm using Ubuntu 15.10 with KDE. There were other bugs referencing the "texture bo too small" message, but they are all very old or marked fixed so I don't think this bug is a dupe.
