REPRODUCIBILITY (% or how often): almost daily
HARDWARE (Jolla1, Tablet, XA2,…): Xperia X
UI LANGUAGE: Finnish
REGRESSION: (compared to previous public release: Yes, No, ?): not as often / not as visible as in the latest version.
DESCRIPTION: When using the browser’s tab view, there is an overlay of the last active page (like this: https://postimg.cc/wtxC7W9c). However this overlay seems to ‘leak’ (in much more transparent/faint version) into outside the browser.
Fe. in this photo of a top-down menu (in the photos app) - https://postimg.cc/nM6f0Y1p - the YouTube logo is still visible over the menu (it also shows over any photos!). Most often it’s logos and UI items that appear faintly on the top of the display, but it can also appear as page elements like boxes or layout elements that appear over any display (here a white border is visible over my background picture: https://postimg.cc/p90g8DTN.
In 18.104.22.168 it seems to be getting worse; I am now sometimes getting white boxes (from other browser tabs or the same tab before entering fullscreen) behind YouTube videos (in fullscreen) as well.
PRECONDITIONS: Happens seemingly randomly, and sometimes the faint overlays show long after the browser is closed.
STEPS TO REPRODUCE: Open browser and several tabs, YouTube seems especially prone to this. Especially after swiping thrue comments, going to full-screen video and back. Then swipe to other apps, and look at the background over pull-down menus etc. Sometimes it’s very hard to notice, sometimes (depending on the background colors) very visible and the newest form, where the overlays may appear over played video, is somewhat obtrusive.
ADDITIONAL INFORMATION: The faint ghosting does not save into screenshots, only shows on the display.
