Created attachment 164482 [details] This image shows the cursor over the dead space that doesn't show neither window. Possibly two very specific issues, affects mostly photographers, i assume. 1- When peeking windows they have a Fade effect, mostly noticeable when comparing two photos by moving cursor over their “preview windows”. 2- The top and bottom of “preview windows squares” are not interactable, which makes it difficult to compare two photos. PS: The fade effect happens on all windows, it’s not because of the gnome program.
Still persists in version 5.92.0 And it can't be circumvented by going back and forth between photos with a single window because most photos have 4K resolution, which requires to be zoomed in order for noticeable differences to be visible.
Still persists in version 5.93.0 Now that I have a better notebook, I've noticed that these fade effects shows the desktop and the window that is not the latest that you've put on focus. I had the internet browser in focus, then i opened two photos, one i've kept in focus (making the browser the second in focus), then when i was going back and forth between these "window previews", I can glimpse the browser, which should have been impossible because that photo was the latest window put in focus. If you have both photos in focus, then it's very hard to see the browser, but it's still there. Meaning: The fade effect is showing more than the latest window in focus during the transition.
Sorry, what is the problem here? I see in your screenshot that one of the windows is missing its thumbnail preview; is that the problem?
Created attachment 165828 [details] Dead-zone AND glitched fade In this video i show the dead-zone space between these two preview window, and after that I show that the fade is glitched, by opening one of the photos, but even then the desktop and even OBS appears for a couple of frames when the other photo is fading-in. I think that the fade is terrible for any short of comparison between two previews, but i guess that might be a setting enabled by default somewhere. Had to be very quick due to the video size limit.
Thanks. I think you may be using the tooltips in a way they weren't designed for, and in a way that's also not ideal for your use case. If you want to quickly compare the content in two windows, with no size differences and no fade effects, the best way to do it it to quickly Alt+Tab between them, This should give you exactly what you're looking for. Can you see if that meets your needs?
Not really. It doesn't have the annoying dead-zone (I wonder why they're different, a bit of inconsistent design). The menu appears right on the center, which is not ideal for my use for comparing photos. And it has the same glitched fade effect when pressing tab. Is there a way of deactivating the fade effect on either of them?
I think it would make sense at this point if we step back and you can explain your actual use case and ultimate end goal, rather than reporting issues with this specific system component that are preventing you from achieving that goal in the way you're currently going about doing it. This is because with the end goal clear, we can figure out the best way to support it. Maybe using the Task Manager tooltips like this is the best choice, but maybe not.
I just want to be able to customize it like Windows (or Gnome with Dash-to-Panel). 1- Being able to disable fade effects when comparing two or more photos. (Doing that with the Image Viewer itself doesn't work because it will reset any zoom) 2- Being able to see any window by hovering the mouse anywhere over their titles (the jpeg shows it). That is the case for the Alt+Tab's preview titles, but it's not the case for the taskbar's preview titles. That is inconsistent, considering they're meant to be the same thing.
Created attachment 165836 [details] Glitched fade effect And there's this glitched fade effect (screenshot from the attached video). It's showing OBS and the wallpaper under it, which shouldn't be possible, since a maximized window is in focus, so it should only fade into the other photo.
Ah but "just want to be able to customize it" is not a use case, it's a means to an end. :) I'm asking you to describe the use case you have that leads you to want to customize that. "Comparing photos" is a use case. As you've discovered, the window preview effect is not the best way to accomplish that goal. So instead of trying to improve the effect so that it can accomplish that goal, I'm suggesting you use a different workflow--for example opening the images up in separate Gwenview instances and alt+tabbing quickly between them. As such I'm not sure there's a real bug here. Can you articulate a bug that's not related to your desire to use the window preview effect to compare photos?
Use cases: You're a photographer and wants to remove the worse similar pics in photoshoots, comparing a game screenshot from two consoles/graphic settings, checking the level of smoothing on a AI upscaled photo in comparison with the original. The Alt+Tab solution is not the ideal solution because: 1. It toggles between all opened programs. 2. The Alt+Tab menu appears on the center of the screen. Bug: If you have any window opened/active/in-focus, then put the cursor over the preview of another window, the fade effect will show for a couple of frames your desktop, and other windows. I assume what was supposed to happen was a fade from the in-focus window into the preview of the one your cursor is over. In other words, imagine this gif showing your desktop's wallpaper during its fading frames. https://ezgif.com/images/fading-gif-creator-demo.gif
Created attachment 165871 [details] Wallpaper during fade I think with this photo it's easier to see the bug with the fade effect. It's showing my desktop, which doesn't make any sense because i have a window in-focus, so it should behave exactly like that gif.
(Now I'm now using Arch Linux btw, but it has the exact same fade bug as Fedora 40 Plasma 6 RC2)
Further proof that the fade is glitch when using that way, is that if you have both windows you're comparing maximized the fade works as intended, just like the gif.
Thanks. I think the conclusion here is that you're using this effect for something it was not designed to facilitate and there are better ways to accomplish that. Alt+Tab will in fact work for your photography comparison use case because: 1. If you hit the shortcut fast enough, the switcher UI won't appear 2. If you use Alt+tilde instead of Alt+tab, it will switch between multiple windows of the same app In addition, many apps have their own built-in image-comparing features. Even Gwenview does, and I have to imagine that pro apps like Digikam do as well. So I would recommend using one of those options for your use case, rather than what you're doing. Because what you're calling a visual glitch is only a visual glitch if you use it for your unsupported workflow; in other cases, it's the expected and intended appearance. :)
Question; If someone is recording a video, purposefully tries to record only maximized windows to hide his private desktop files, but the fade effect (as intended) exposes such desktop files the person was trying to avoid. Wouldn't that be a privacy problem? Is it stated somewhere that the fade will reveal your desktop for a couple of frames? I still can't comprehend why the fade is not between the windows you focus (crossfade). It's not like everyone minimizes a window before opening another, which would made the fade look perfect.
I still wonder if the fade effect ignoring the "most recently active window" really is on purpose, because otherwise it would be an smooth cross-fade. The fade starting from the desktop doesn't make any logical nor artistic sense.
