Description (last modified by )
Hi I have lots of screen tearing, specially when I move or resize a window.
My laptop: Dell Latitude E5570 Intel I5-6300U Intel HD520 (Skylake GT2)
It happens in Beta4, Beta5 (tc0) and in nightlies (64 And 32 bits). It happens with whatever resolution, colordepth or refresh I've tested. My last test is on hrev58046

I use a HP pavilion 17 - g142ng with intel Skylake GT2 and have no problems with 1920 x 1080 (SDC 17,3") haiku 64bit nightly Even Brightness-Slider is working just fine!

It is really hard to notice, I think it is no bug, it is an enhencement or just normal! I have this on all other systems as well!

Hi, this is normal indeed. This is because redrawing intersects with the screen refrehlsh taking place. Normally one would enable 'sync to vertical retrace' so redrawing video or a window happens outside the users view. Best used with double buffering: drawing in back buffer and then switching back- and front buffer during retrace'. I guess since we have no hardware acceleration and mostly no video overlay it's not really possible though.
