Zooming with canvas zoom mode/relative zoom mode is veryy laggy/not responsive, sometimes just not working.
I was thinking it was a performance issue but if I try to use mouse or trackpad it works just fine. Discrete zooming and Rotating mode works just fine with both tablet and mouse.
i tried creating new shortcut, using different keys, using different profile and enable "right click pentab event", still not working.

help. its weird bug I don't know why.
I'm using huion 950p.

thank you.

Something similar to this has been reported and is being investigated: https://bugs.kde.org/show_bug.cgi?id=414576

Can you try the latest nightly build at https://binary-factory.kde.org/job/Krit ... ows_Build/ and download the portable .zip package to see if that helps? (This is not suitable for normal/daily use.)
Can you also try turning Instant Preview on/off and switching between Open GL and Angle (restart required) to see if that makes a noticable difference?

Thank you.
Yes. The problem was exactly as described in 414576 report.

But. The problem is already solved. (i didnt change anything, as i recall. still using same krita installation). somehow the zoom is working normally again today.
So I guess my driver is the problem... ?
anyway thank you for responding to this thread.

EDIT: Nvm. it happened agian. it seems restarting my pc solves it.
