What app(s) do you see this in? Do you have any scaling applied?
Comment 2 Eddisch 2025-10-08 22:12:32 UTC
I only noticed it in Yandex browser, falkon browser and discord (equibop). I didn't see the hand cursor being used in other applications.

Also, no scaling.

I notice all of those apps are Chromium-based. I can't reproduce it myself in Chromium 141.0.7390.65 (from Flathub), though, with current git master of KWin. This would suggest it's been fixed in a newer Chromium or KWin version.

I'd ask you to re-open this if you find that the issue still happens with Plasma 6.5 and Chromium 141.0.7390.65 or later. Thanks a lot!

No problem! I tried this in system settings too, and it happens there too (with the I-beam cursor) so the iissue isn't chromium. I'lll upgrade to Plasma 6.5 when I have time and say something if it still happens.
