and i guarantee you... it does affect first draw now. all the dropdown menus
from app i see now are blank empty space indefinitely UNTIL i mouseover them to
force a redraw.
this is all a matter of race/timing so different people will see different
results based on many factors (cpu core count, clock freq, cpu speed, toolkit,
app, drivers etc.) but... this does cause a problem, so by design it has flaws.

Re: [E-devel] [EGIT] [core/enlightenment] master 15/17: redo X first_damage logic
Ok. If there is no "timing" issue of the first draw, then my concerns are unwarranted. Fair enough. Just trying to be sure you have considered All possible options & consequences ;) Guess I am just fishing for some reassurance that this is not going to affect any initial "showing" of the app... Ignoring a "first draw" could (potentially) be a disaster If you say it does not, then (for now) I'll take you're word for it ;) (no offence intended in any way...just wanting the future to be bright) dh On 30/01/14 18:02, Michael Blumenkrantz wrote: > Given that this does not affect the timing of the draw, I'm not sure > how you are arriving at this worry. > > On Thu, 30 Jan 2014 17:54:24 + Chris Michael > wrote: > >> Nice onejust worry that this will affect the First draw... >> >> If I am wrong, happy to admit that ;) >> >> Keeping the region is good ... but let's not lose the initial draw >> (if it can be helped).

Given that this does not affect the timing of the draw, I'm not sure how you are arriving at this worry.

Re: [E-devel] [EGIT] [core/enlightenment] master 15/17: redo X first_damage logic
Nice onejust worry that this will affect the First draw...
If I am wrong, happy to admit that ;)
Keeping the region is good ... but let's not lose the initial draw (if
it can be helped). Region 1 is sort of "initial show" ;)
