Short description of error
OK, noticed the scroll bar in preferences seems to be invisible. Seems to work everywhere else. I loaded factory settings as a test and it still does it.

Exact steps for others to reproduce the error
Open preferences and go to addons.

Open preferences in separate window for it to start showing.

more info:

  • it will also appear if you adjust the size of any editor
  • even though it's invisible it still responds to clicks

It seems that this is caused by a scaling fix in 2.7 (https://developer.blender.org/T47047). However I was unable to replicate the issue 2.8, even with the fix in T47047 removed, as shown in the image. Patch to fix this bug is attached.


I will be on later today, about 10 hours from this post, to try and submit the patch through the proper channels according to https://wiki.blender.org/wiki/Process/Contributing_Code.

Thanks!
