PDF reading encounters flashes of later content

when i read a pdf in zotero, it sometimes flashes and that's very annoying. i used my phone to record a video and saw that the flash was actually the content of the pdf itself, only that it's on the last few pages.

when i enter the troubleshooting mode, the flashes seem to disappear. if not in troubleshooting mode, flashes appear randomly while reading & when i minimize the window and then maximizes it & when i go to my library page and return to pdf.

here's the critical frame from the video. seeing an EEG cold brain flashing is really annoying and creepy.
  • I cannot reproduce (mac and linux, 7.0.13 and 7.1-beta.16). Do you see the same in troubleshooting mode (Help > Restart in Troubleshooting Mode...)?

  • toubleshooting mode makes it all good. actually i think always being in troubleshooting mode should be just fine for me since i dont really use any plugins. but it would be nice if the default mode could be fixed.
  • But do you have any plugin installed? Troubleshooting mode is only for troubleshooting.
  • i once installed a translation plugin, but it was so heavy and unstable so i disabled and deleted it. now there is no plugin on my zotero. maybe i should try re-installing zotero (?)
  • I don't think you need to go that far. If a dev sees this thread they will be able to provide a better assistance than me.

    @riverren: To start, try updating your graphics driver. If that doesn't help, you can try setting layers.acceleration.disabled to true in the Config Editor in the Advanced pane of the Zotero settings (which is one of the other things Troubleshooting Mode does) and restarting Zotero, but that will slow down graphics rendering in Zotero, so you shouldn't do that unless you can't fix it any other way.
  • actually after being in troubleshooting mode for some time, now that i use the default mode, the problems seems to have disappeared. thanks for caring at all, poettli <3
