X.Org Server 1.18.3 Adds an Important Performance Fix to the “Present” Extension

X.Org Server 1.18.3 appears to be a small point release that fixes a total of eight issues reported by users since X.Org Serve 1.18.2. Among the changes, we can notice two XWayland improvements, such as a temptative attempt to support viewport in vidmode, as well as removal of any frequency data in the mode name. Polaris PCI IDs have been added to DRI2, glamor received some improvements to alpha textures, the verbosity of GetModeLine debug messages was reduced for vidmode and Xext, and the hardware cursor is now hidden when needed for XFree86.
