Reproducible graphic artifacts: Triangular projections of graphics, picked up from one or more megaprims within the view area, tend to radiate from the focus point of the user camera when this "bug" is triggered. So far it has been triggered only in one area (Northwest corner of Huineng region). Hypothesize that the artifacts may be triggered in proximity to more than one layer of megaprims within the viewing angle. Artifacts seem to persist until the avatar teleports away from the area in question, and do not tend to return unless the viewing avatar moves to a fairly specific point (SLURL provided below) within the suspect area, and happens to redo a similar set of camera moves while standing in that spot. Possibly unrelated phenomena: The Chat/IM and User Interface aspects reported may be a one-time issue. Will continue testing and add further details and/or reproduction conditions if this repeats. Have attached screen captures to illustrate the behavior that first grabbed my attention. The first time this occurred, I spent several minutes taking screen caps of the "textured triangles" phenomenon before realizing that I was out of communication, and that the avatar was locked in place. Behavior appears to have corresponded (or perhaps merely coincided?) with a disconnect from at least some of the region's servers. Viewer did not crash, but avatar locked into position, map became unavailable, IMs could be sent to Friends and open groups, but no sign that they were received (though individual IMs to friends did echo in the Comm Box). Music from the region's media channel continued to be available until the viewer was closed. Viewer was able to make a voluntary, normal, clean shutdown with no crash. As stated, these particular anomalies were not reproduced the second and third times I managed to recreate the conditions and reproduce the artifacts in question. 1st two attachments show the bug at it's most glaring, first one also shows interface and appearance of the blank map menu. The third attachment was captured from a slightly different rotation of the camera and a point where most of the triangular artifacts had disappeared from view. Have several other screen caps from this incident on file if they are of any interest for analysis. No residual aftereffects were noted when I relogged into SL, using the current Release Candidate – 1.18.5(0). The next login, where I managed to reproduce the artifacts in two distinct episodes, was made again using the First Look: Windlight version named in the Environment field. Reproducing the "phenomenon" I cannot think of anything I did specifically to bring on the issue. Before it came up I had been editing the appearance of some attachments while standing on a "pose stand" at my Huineng store. My avatar appears at the center of at least one of the screen caps attached below. Shortly after completing the edits – which were done to address another minor bit of oddness relating to the alpha bug and an invisiprim script used to hide the avatar heel in a pair of high heels I had made – the "phenomenon" of the radiating triangles of textures started to show up. Second and third occurences were created by going to roughly the same location (lower floor of atelier dropdeadcute), and swinging the camera first outside (toward the west of the sim), then rotating the camera from a spot suspended somewhere above the Linden Road that bisects the region to look back into the store and focus on the avatar standing inside. Second (and third) occurence: Logged into SL for a second time. Moved from the location that had been set as "Last Location" (same as on first run of viewer, FL WL viewer did not log my location from the previous run). Went to same location where bug occurred on first run. Took various photos. The first run of about 25 pics were gorgeous and no artifacts. Swung the camera outside the area where my avatar stood to take some pics. When I swung camera back to the avatar the artifacts reappeared. This time the avatar did not lock up. Used Alt-LeftMouse to set focus-pivot point for camera. Most artifacts seemed to center on the camera's focus point, not necessarily the center of screen. Artifacts continued to appear despite avatar and camera movements until I teleported to a new location within the same region. At that point appearance returned to normal (for WindLight).
