bug#29691: 25.3; Flashing characters in large window and large files

[Sven Fischer]

[-- Attachment #1: Type: text/plain, Size: 5227 bytes --]

Hello,

I have the problem that parts of the edited files are flashing
significantly. This occurs especially when using large windows. It is
reproducable, but not always observable. I could not figure out, what
exactly is triggering the behaviour. I try to attach a screen recording
showing the error for reference. In the video I do nothing, pure emacs idling 
on a nxml file.

Regards,
Sven

Are you still seeing this?  Did you find out more about the conditions
under which this is reproducible?

More information was requested, but none was given within 10 weeks, so
