The KDE team have today announced the release of the Plasma 5.19 desktop environment with a 'Polished Plasma' codename.
With a firm focus on making the whole of the Plasma desktop more consistent, they've gone through many elements of the Plasma UI to attempt to unify the designs of widgets and desktop elements on top of giving more control and configuration options. Some of the updates include:
- Info Center saw a redesign to be consistent with system settings, it also has a new feature to give you a readout on your graphics hardware.
- KWin Window Manage now supports subsurface clipping, which should reduce flickering in many apps. Wayland support was improved as well to include working screen rotation for tablets and convertible laptops.
- The Discover software centre has improved the Flatpak package format support, to allow removing Flatpak repositories in an easier way. Discover also now shows the app version.

I've been using KDE Plasma for quite some time now and for the most part it's been a great experience. Ideal for users who want a lot of customization options available out of the box, as opposed to GNOME being quite simple in comparison but it comes down to personal preference as always. Great to see big updates like this focus on a good out of the box user experience too.
See the full announcement here.

Quoting: ewertonuriasI migrated to Linux in 2012, and from 2012 to 2018 I had problems with screen tearing in all friendly DEs, in all video cards I bought (GTX 460, 660 and now 960).
Force and Full Force Composition Pipeline solved the tearing, but I felt the loss of performance.
In 2018, I found a solution, was to use Xfce + Compton + Command "compton --backend glx --paint-on-overlay --vsync opengl-swc", this removed the tearing.
In 2019, I tried Plasma, and I was surprised, KWin removed the tearing, and the stuttering that I had but didn't know.
For my case, Plasma has become the best option for games, since I disable the "Allow applications to block compositing" option in the Compositor.
I'm thinking of trying out RX 580 next time.
I use an RX 580 on Manjaro's KDE and its been a butter smooth experience so far. The rx 580 worked perfectly out of the box. Can play every game i've thrown at it. All of the cards sensor data is easily accessable as well.

Now, if only KDE PIM could get some attention...I mean, there hasn't been any QA since Akonadi came into play, like 8 years ago.
This has been 8 years of hell when using the calendar (and kmail too; take a look at that 9 years old bug https://bugs.kde.org/show_bug.cgi?id=283682 ).
Somehow, for 8 years the Korganizer app did not had a single feature added (apart 2 redesign of its events), but still is the best calendar app that exists on Linux.
The horrorifying Nepomuk app was killed after years of tormenting their users ; please kill Akonadi (with fire) now.
For new users, Plasma might be as great as we want (it is!), in the first month of use when they'll lose access to all their emails, events, tasks and rss feeds history, you can bet they will flee Linux running to where they came from.
KDE PIM needs new developers that dogfood their app. Too bad throwing money at the kde ev did not meant I could ask for KDE PIM to improve..and there are not bounty program that list Korganizer that I know of.
Oh well.

I really do like KDE... I might be alone on my planet, but there is tearing all over the place, even while gaming with Vsync ON. What have I done to deserve such a treatment?! 
I tried all the workarounds I could find, but none of them seems to solve the issue... When I switch back to Gnome... Problem solved.
It's probably a great experience for those with AMD GPUs or with Gsync/Freesync Monitors (I tested on a Gsync laptop and it's doing an awesome job), but other then that, I've had zero success thus far...
It's the only show stopper, for me, to go full Kubuntu. At least, there is no tearing when I use Steam's Remote play...

What have I done to deserve such a treatment?!I've never had any tearing with KDE on my Nvidia desktop or my Intel laptop, which both have standard fixed refresh rate displays. So neither AMD graphics nor variable refresh rates are necessary requirements. There is a triple buffering option somewhere, but you've probably already tried that.

Anybody here that use KDE, has an NVidia gpu and uses gsync? Does it work properly?

I just don't understand... Kubuntu 20.04 clean install... I don't have some weird hardware config... Ryzen 5 3600, Gigabyte aorus motherboard... ASUS GTX 1660 Super... Why?
Read somewhere there was an issue with KDE/Nvidia with the actual kernel. Some said upgrading to kernel 5.6 was the solution, but I like to keep my gaming setup as stock as possible... Oh well. It's easier for me to switch back to gnome, for the moment. I might keep Kwin around, for testing purpose.

You can check the Display and Monitor -> Compositor -> Tearing prevention ("vsync") option.
I had also tearing problem till I found this.

Tried them all. No success.
I could turn on Force Full Composition Pipeline, but it generates ugly micro-stuttering, and it doesn't solve tearing issues in The Witcher 3. If I turn on the in-game Vsync, it becomes a stutter fest. Lose-Lose. So, FFCP is not a solution, for me, either.
