SUMMARY
In krita 5.3.0 prealpha (git 55a937c), the hitboxes for assistants are very small when using a 4K monitor. This means I more often than not end up activating another assistant when I want to adjust a perspective assistant's handle. I’m hoping that the hitbox could be increased because I'm not able to make pixel perfect taps with a pen tablet. 

STEPS TO REPRODUCE
1.  Open Krita on a Windows machine with a 4k monitor
2. Activate the assistant tool
3. Create any type of assistant
4. Try to move any of its handles and note you'll likely create a new assistant more often than you'll hit the handle.

SOFTWARE/OS VERSIONS
Windows: 10.0.19045

I haven't yet confirmed it to happen, but I suspect its related to DPI scaling. I'll look into it later.
