This is only to say that since a few months ago (?) Emacs redisplay seems to be broken. I do not have a recipe, but I would be surprised if no one else sees this at all. If I create a new frame (e.g. C-x 5 f) that partially obscures an existing frame, for instance, and the select that partially obscured frame (e.g., by clicking its title bar), so that it is raised again, the part of the buffer that was obscured looks wiped out (blank). And repeated C-l does not fix this. My workaround is to thumbify and then dethumbify the frame. (Probably iconifying and deiconifying would work too, but I do not iconify anymore.) This does not happen systematically - just sometimes. Again, feel free to close this for its lack of reproducible recipe. Just wanted to give you a heads-up that redisplay is somewhat broken now.

I will try to pay attention. I don't think that my actions in Emacs beforehand are necessarily related - I have seen this happen also when returning to an Emacs frame after using another Windows app (window mgr window). I don't change things like display-time (I show it, normally), but I do sometimes show other info in the mode line temporarily (returning to my usual mode line, with display-time).

I understand. If there is no way to correlate the source changes made with the bug report, and so lots of such source changes could affect this, then the bug report cannot help. Feel free to close it in that case. Hopefully another report will come along, with more precise info. Maybe, when such wholesale optimizations are made in the future, some debug code can be added, so that symptoms such as I reported can more easily be traced to particular source changes? Is that feasible? My impression is that this is not the only bug report about failures to redisplay properly in Emacs 25. Seems like we have, on the one hand, lots of redisplay optimizations implemented together, or within a short timespan, and a fair number of redisplay problems reported, and no specific, operational connections made between the two. If so, that's too bad.

Is that > feasible? We have the debug code. I myself use it all the time, and several times asked people who reported bugs to enable it and show the output. But it produces a lot of output, so it is only feasible to turn it on when running a reproducible recipe. Which we don't have in this case. > My impression is that this is not the only bug report about > failures to redisplay properly in Emacs 25.

There were indeed several reports about redisplay problems, related to those changes. They were all fixed, AFAICT, because each one eventually succeeded to find a recipe for reproducing the problem.
