contour-0.2.1.1541-prerelease-ubuntu_20_04_amd64.deb smooth movement, no flickering, no jumpiness. Also no measurable cpu load increase,
looks fine to me!
Build 1526 is just fine. But i was actually reducing CPU load of
contouritself. I did not even look at Xorg process’s load, lol.I try to investigate on that one, too. Can’t promise any immediate magic though. 😃
just tested alacritty. No measurable increase in top. Also no flickering. The window-over-pointer drawing was my guess from past experience what part of the issue could be. I have not done any debugging on that ( and wouldnt know what to do anyway)
