Wz4 Question: Ops stack occasional slight flickering curable?

Skinnytorus opened this issue · 2 comments

After 'showing' some animated Ops, this and other Ops in Stacking view start to flicker occasionally. Can it be cured?
I thought it was a screen sync issue and tried forcing sync for wz4 in Nvidia driver, but that doesn't seem to work...

The Werkkzeug4 GUI (unlike Werkkzeug3) uses plain Windows GDI calls which draw directly to the screen without any double buffering (at least if Desktop Compositing, i.e. Aero, is off). When animated, Ops will continuously redraw (in case their caching state etc. changes). So, short version: this is expected and not properly fixable without using either double buffering (which forces GDI to use software rendering and is much slower overall) or very detailed dirty region tracking (which is a pain in the ass).

OK. Thanks for commenting.
