I installed a fix to make it faster -- but I can still create a file which takes minutes to display -- it just requires a line which is veeeeeeerrrrrryyyyy long. In my case, that specific .gif file still takes 4-5 seconds to display even with my fix. So the fundamental problem of redisplay being O(n) to the length of lines in the buffer is not fixed, and I don't know how to solve it (and we certainly shouldn't do this BTR). > Then there's the problem you reported, where redisplay took a few > seconds, and that was long enough to be pre-empted by selection > requests from Klipper. Yes, that is a different problem as such -- but I guess we can find other cases where some activity is stalling redisplay when redisplay-dont-pause is nil. So I would still like to put some upper limit on the time where we force a redisplay to actually update the screen. > That is also a serious issue, but it is due to a Klipper bug and we > can address it sufficiently by telling users "Update your KDE or don't > run Klipper". Isn't that so? That is a work-around for one manifestation of the problem... -- Kim F. Storm http://www.cua.dk
