Good stuff, I've been able to reproduce it now - and understand the problem. However the solution is not obvious / easy :( I've attached my stacktrace (NB line numbers may be tiny bit different as it was run on my own development branch) I forgot to mention you need to break on gdk_x_error to (see http://wiki.debian.org/HowToGetABacktrace) There's basically a conflict between the tile map drawing & and the gps keep it on screen which are done in separate threads. They both generate vik_layer_emit_update events, which eventually call the low level pixbuf to screen. I think If the timing is such that both of these happen near enough the same time the X server (quite rightly) doesn't like it. Potential solutions: . Use your workaround :) . Some kind of lock/semaphores in the viewport to serialize the X drawing . Some kind of redesign so only one thread updates the display . Something simpler (that doesn't come immediately to my mind......) These are a bit more involved than my level of Viking understanding. [Plus I'm really busy for the rest of this month] HTH. _________________________________________________________________ http://clk.atdmt.com/UKM/go/195013117/direct/01/ We want to hear all your funny, exciting and crazy Hotmail stories.
