The pen tool is practically unusable on something like my 13.5" Surface Book 2 + Corel Painter 2022 (and and all past versions I presume). The reason being the curve controls and nodes are so tiny on those dense pixel displays that it's not possible to click on them (or touch them with a pen tip). It doesn't seem like this part of the application respects Windows' graphics scaling (I have mine at the OS recommended 200%) even though the painter UI in general does.
A laptop capable of running Painter 2022 effectively will likely be a high end one and high DPI screens are likely very common in this category of machine. As it is if I need to do some vector work I need to move the image to Photoshop or wait until I return to my desktop where I have a lower resolution monitor. It's ironic that I have to use older equipment to use a feature!
Common problem with high DPI or 4K displays. Play around with Windows scaling- it will effect your entire system though. Everything was too small for me to read on a 13" laptop so i increased it I think.
Thanks to you and DougS for the suggestions. Scaling the text size in Windows helps in some dialogs and not in others. There must be some hard coded font sizes in the code because if you go to Edit>Preferences>Keyboard Shortcuts (for example) things in there don't respect the text size scaling at all.
Neither does it doesn't solve the issue with the pen tool handles.
In 2022 this is a really bad look as laptop and even desktop display densities are ever increasing. With some of these dialogs we're not even meeting basic usability standards much less providing accessibility for people with worse vision problems.
