Opening the find/replace dialog causes editor text to become blurry

[Mehgugs]

Issue Type: Bug

When I open the find/replace dialog the editor text becomes blurry until closed/restarted.

Tested with different themes and extensions disabled.
Reloading the editor does not fix/reset the issue only fixes if you restart it.

After some further playing around it seems to occur when opening any dialog except the top menu bar (File Edit Selection etc...).
