Window switcher shadow persists until overdrawn, after latest updates
What Happened?
I've found two issues:
- When you have at least two windows open and there is a desktop background visible between them and you hit alt-tab then some strange artifacts are present after switcher disappears, please see the video attached,
- I quite often make use of keyboard shortcuts for tiling windows either to left or right. When you use alt-tab this function stops working until you change focus to other window or display multitasking view.
Steps to Reproduce
- Open at least two windows
- Make sure there is a space between so you can see the desktop background
- Hit alt-tab and observe strange shadow artifacts on the screen
- Now you can't also tile windows with predefined shortcuts until you change window focus by hand

Expected Behavior
No artifacts should be present and window tile shortcuts should work as expected after using alt-tab.
OS Version
6.x (Odin)
Software Version
Latest release (I have run all updates)

It's related partially to this one: https://github.com/elementary/gala/issues/1401. This bug exists for over 3 months now...
As for the first point regarding strange artifacts, I guess it could be related somehow to this issue. It still persists in eOS 6.1 (and it's very irritating). Waiting for OS 7.
@activey You can use https://github.com/small-tech/catts This solves this issue. This artifact is a part of Gala Alt+Tab and does not seem to be fixed soon. HAHA.
The shadow also persists when moving a PIP window around so seems to be related to certain window types rather than the window switcher specifically.
Just FYI I can reproduce it even if there is no gap between the windows. In fact I see it all the time with maximized and overlapping windows, too.
About point 2. - you can also get the shortcuts back by pressing Super twice (at least it works in my case - it quickly shows the keyboard shortcuts overview).
@janxkoci yeah, shorcuts are back when you for example move the window by "hand", but still, this is way annoying :P
@activey alright, although I prefer to press some key rather than reach for a mouse...
i have the same issue with gala in fedora 36.
is there some way to disable drop shadow in gala ?
Is any update on this problem? I can reproduce this problem in OS 7 too. Instead of elementary OS alt tab, the catts should be shipped by default in elementary os 7. (As a gala plugin). Catts does not produce this artifact in alt-tab switcher in any version of gala.
@arfayjie it probably wont happen soon as there are more important matters like selecting folders with a single click: https://blog.elementary.io/updates-for-november-2022/
@activey this is an annoying bug. Hard to use elementary if such bugs persist. It’s been more than 6 months. And it is the same for OS 7. How elementary team can ignore such bugs which should get the maximum attention. They can atleast ship catts until they fix it.
Hey guys, please understand that you're spamming everybody that's interested in this issue.

Please also understand that someone who likes working on Files for example might not enjoy and/or have the expertise to work on Gala. Most of this happens in people's free time.
And then ask yourself, what have I contributed?
@peteruithoven, you have misunderstood my comment then. And also this is not a question to ask myself, what have I contributed? I have more contributions towards research than an operating system. Elementary OS claims to be user friendly mac and windows alternative. And there are some minimum requirements for a user to use it. It’s really an important issue. But I also provided the solution. Catts plugin doesn’t create this issue at all. Elementary os can ship it by default. That was what I meant. I understand people work on free time. So, why do we need to reinvent the wheel? If we already have a working solution.

@arfayjie Great idea! In fact, it already has been done: https://github.com/small-tech/catts#catts-is-now-part-of-elementary-os.
Unfortunately, this issue is a bit more deeper, and hasn't been fully chased down yet. I agree that the issue is frustrating, but we don't have much to gain by complaining that something takes a long time to resolve. Additional logs, recordings, and screenshots would be much more helpful and constructive. That way we can further diagnose and hopefully resolve the issue!
@kgrubb I got your point. That’s true. Actually I was trying to give some input here. I didn’t check the logs yet. But this is what I found so far.
If you use catts and install it as gala plugin then you don’t see the artifacts. So what I can conclude is that the way it is implemented in elementary os is the starting point for debugging.
May be @davidmhewitt @danirabbit would know it better. I will add some screenshots (or may be screen recording soon).
We already know what the bug looks like. Which logs do you think we should provide to help move this forward?
