Rounded corner display issue with WezTerm in KDE 6.3
I am using Arch Linux
KDE + Wayland environment 125% scaling
I am using aur/kwin-effect-rounded-corners-git, built with the latest git code
The display in wezterm looks like this, and the rounded corners don't seem to be working
Rounded corners display correctly in KDE 6.2, but not in KDE 6.3
However, other software displays correctly, for example, Obsidian works fine
Can you check if transparency can be a culprit?
Turning off the transparent background of wezterm doesn't change anything.
However, if you disable the "No titlebar and borders" option for WezTerm in Window Management -> Window Rules, the rounded corners will appear above the border
But this isn't aesthetically pleasing, I'd like to continue hiding the borders
On KDE 6.2, Wezterm still has rounded corners after hiding borders, but it doesn't on KDE 6.3. There may be some KWin updates that need to be adapted
@a15355447898a Do you still have rounded corners in your Desktop Effects list?
I ask because I have the same issue. Rounding stopped after an update 2 days ago, the preferences in Desktop Effects disappeared. They don't appear through reinstall either. Arch Plasma 6.3.1

I am currently still on KDE 6.3.0, and the rounded corners effect is still present in the Desktop Effects list.
I think I have the same issue so I'll add some further info and a possible solution:
Running on Plasma 6.3.3 and Wayland for me this only happens with terminals and only when the program is being tiled on a separate monitor (it works fine on the primary monitor). This happens no matter the opacity of the terminal and I tested it on alacritty and konsole.
Great thing is that the problem disappears if I switch to X11 so it might be an nvidia issue? (I'm sadly on a team-green GPU)
Hope this helps.
I found an interesting detail. This happens because of scaling; at 100% scaling, everything works perfectly. It even works on different monitors: on my laptop, I have 165%, and on the external monitor, it's 100%. When I drag the window, I can see how the issue appears and then disappears.
KDE 6.3.4, Wayland, 150% scaling. I notice that the rounded corners show up differently in different window sizes, the demo app base on electron running on wayland.

Edit: But if the app is running on xwayland, there are no display issues.
I've got those rounded corner issues for all app in general
I removed KDE-rounded-corners which I had installed previously, and loggedout-in again, but the problem persists. I think the SVG for the header needs to be modified.
So I think it's not necessarily a KDE-Rounded-Corners issue.
Alternatively, we could try this effect https://github.com/taj-ny/kwin-effects-forceblur
edit: it doesn't fix anything
I have the same issue as @CAB233 . This is reproducible with Obsidian and other Electron apps in my case.
KDE Plasma 6.3.5, it works now!
In my case WezTerm still has problems with rounded corners. I'm kde 6.3.5 and have rebuilt aur/kwin-effect-rounded-corners-git
have you tried turning the effect off and on in Desktop Effects?
It's still not working.
On my device, I set Kitty to 'hide_window_decorations yes' and I found that the rounded corners work fine when it is opened in any window size with an 8:5 aspect ratio, but when I change the window size or open it in a different ratio, it fails.
I have nothing really useful to add, except that to say that I am also facing this issue on Arch and KDE Plasma 6.4.4 on Wayland. It seems to work fine for most programs, like those using xwayland or wine, while things such as System Settings have sharp corners. Though with 6.5 around the corner, the solution I suppose will be built in to Plasma itself soon enough.
I’ve investigated the problem with rounded corners not working at fractional scaling (e.g., 175%) and found that the issue is directly related to native window shadows. When “Use Native Decoration Shadows” is enabled, the effect’s corner mask does not apply to the shadow region, so the corners appear unrounded at non-integer scales. With custom shadows enabled, everything works as expected.
For now, the only reliable workaround is to use custom shadows.

That worked for me! Thank you!
@nullptroma Thanks for checking this out. I have optimized the roundness of native shadows for the Breeze decoration but I suspected that others might have issues.
