Blurriness when browsing images in fullscreen

Post by faltonico »

Hello,
Is there a way to disable/remove the blurriness the images get momentarily when scrolling through a gallery in fullscreen?
I mean, i think it might be related to caching, but i don't know which is the setting i need to tweak so i don't notice the blurriness. It is a very minor thing, but I am that annoying kind of guy.
I have a decent PC, and i don't think i couldn't handle faster rendering. It happens with big images mostly (around 20+ MB), the thing is that this doesn't happen with other paid versions of image browsers that i "borrowed" for testing.

Thanks again for such a fantastic job you do!

I'm pretty sure your image resolution is higher than your monitor.
There is "High zoom quality" feature in app:
  • settings
    Settings > View > High zoom quality
    - Zoom out [Bilinear]
    - Zoom in [None]
  • state
    Viewer > View > High zoom quality
    state always resets to enabled on new tab open
try to set it Zoom out to None, if it does not help guess you have to provide sample file

Thank you for the reply!
Yes, the images are way bigger than my monitor (9504x6336), and swapping the zoom to none didn't seem to improve the situation, at least not a significant difference. And the blurriness is not tied to a particular image, sometimes it shows and sometimes it doesn't, but it does appear more often when scrolling in quick succession.

Also! while testing, i ran AMD's capture program to record what i saw, (cause i am too slow to pick a snapshot of the blurriness), and then i was looking at the images back and forth and the program crashed!
This is the dump file:

i couldn't send the automated crash report, i'll have to e-mail it.

Another also, I don't know if i can post a sample image here, cause technically, it is copyrighted, it is a cosplay artist (safe for work mind you).

Thanks again for you help :D

is it jpeg? Do you have tried to disable 'Settings>View>Misc>Two pass rendering'?

That did the trick! They were jpeg, and I didn't even know what that settings did.
Thank you very much!
Now it takes a tiny bit longer to scroll between images, but at least i don't find it off-putting as the blurriness.

BTW the day after tomorrow this account will be 10 years old, thank you very much for your continuous work and support. I has been amazing!.
