--- Comment #8 from Michał Staruch <michal.star...@gmail.com> --- Created attachment 141366 --> https://bugs.kde.org/attachment.cgi?id=141366&action=edit Comparison: shape with all WM_MOUSEMOVE points painted I've also added shape with all the WM_MOUSEMOVE points painted and counted, for comparison - drawn during about 1 second. Point coordinates were gathered into int vectors when handling input messages (in about 1000 Hz rate), then painted (and vectors cleared) to canvas on every WM_PAINT (triggered by simple timer at about 60 Hz rate). I've pushed it here, if anyone wants to take a look at the sources (nothing fancy, just quickly coded illustration of the idea, based on Microsoft template): https://github.com/MichalStaruch/WindowsMouseReader -- You are receiving this mail because: You are watching all bug changes.
