Can you try if this problem happens also with kpat from flathub? https://flathub.org/apps/org.kde.kpat

Interesting, you're the second person reporting this on Fedora, can't really reproduce it myself, so for now i'm blaming something on Fedora. But no idea what it may be, some part of the graphics stack?
I can see the same bug on OpenSuse Tumbleweed, since Plasma 6.2. It's especially visible in Spider when dealing a new row of cards. The bug is still present with KPat 24.12.0 - Plasma 6.2.4 - KF 6.9.0. This only appends on Wayland with fractional scaling (130%, 125%, but not 100% or 150%), not in X11 even with 131.5%. This bug, or a similar one is also visible on Comic Alpha 3 and 4 at 125% scaling, but not 100% (tested on OpenSuse). It does not affect Gnome (even on Wayland @ 125%) nor Cinnamon (on Wayland card movement is not perfect @125%, but it does not stay after the card is released). In any case, interacting with the application menu redraws the window and all the moving artifacts disappear, until you move another card.
On my up to date Tumbleweed (with wayland @130% scale (4k display), Plama 6.2.4) I've tried different flatpak commits. Only the last one is affected: Commit: d2e257ff3b439003c136eff561adfde17eed018539060b7435fd9298bd77ed44 Parent: 49b3c0022514b82e94bd865deea18ff2cd208eca834b50e211cd4036beade445 Subject: Update org.kde.kpat.json (d30499f7) Date: 2024-12-11 17:11:48 +0000 The KPat about menu says: KPatience version 24.08.3 KDE framework 6.9.0 Qt 6.8.1 The previous flatpak commit is bug free: Commit: 49b3c0022514b82e94bd865deea18ff2cd208eca834b50e211cd4036beade445 Subject: Update libkdegames and kpat modules (0c32fc9d) Date: 2024-11-08 02:45:06 +0000 The about menu says KPatience version 24.08.3 KDE framework 6.9.0 Qt 6.7.3 So the bug might be in Qt 6.8 rather than Kpat.
