My previous OS was Ubuntu studio 18.04 where drawing worked fine, but some features were lacking or caused crashes like Scripter or Detach canvas. This and also the fact that there is a functional UI for tablet settings in Kubuntu made me change versions. But now the brush lag is unbearable even if I use mouse when CGA is on.
I got gf 1080 and have no lag issues in Photoshop nor in Ubuntu 18.04 the lag wasn’t anything close to what I experience in Kubuntu.
Also the only Krita versions that work at all, are the nightly builds as 4.3.0 version gives me error:
ASSERT (krita): “screen < QGuiApplication::screens().size() && screen >= 0” in file /root/parts/krita/src/libs/widgets/KoToolBox.cpp, line 51
Are there any possible solutions for this so I can zoom and paint?
