render problem on ipad4

[Herbert]

Hi guys,

I tested my game on ipad4, and sometimes a few sprites can not be displayed(most of the time is the bg image), but the rest are rendered normally,
since it does not happen every time, and it only happen on ipad4, moreover, it does not pop out any error, it's really hard to find the cause,
does anyone know what could be the possible cause to this sort of partially render problem?

Are the images in a texture atlas? Or individual images?

[Herbert]

hi alex_h

it is atlas

[ivan.popelyshev]

what version of pixi? we had something like that in 4.0

[Herbert]

4.3.4

[ivan.popelyshev]

do you use masks or filters?

upd. try call renderer.gl.flush() after each render()

[Herbert]

I use both in my project, but at the begining of the game, the filters is not used, only the mask

[ivan.popelyshev]

try call "renderer.gl.flush()" after "renderer.render()"

[Herbert]

by the way, I remember in early version 4, mask won't work in my project until I set
renderer.maskManager.enableScissor = false;
could it be the problem?

[Herbert]

ok, I will try when I get my ipad4, it's not around me now.
so if "renderer.gl.flush()" work, should I keep it in my code?
does it have any side effect?

[ivan.popelyshev]

no side effects. we added it in 4.4.0, i think, there was a problem like yours. Oh, and I did found error in masks , it was critical fix of 4.3.5 - you can download it! its just like 4.3.4 but with fixed masks

[Herbert]

sorry it takes so long, as I tested, neither call "renderer.gl.flush()" or update to 4.4.3 work, there are still missing objects sometimes,

but I found out this only happen to "the safari on the ipad4", it is quite limited actually.

and the missing objects will show up after resizing (turning the screen portrait)
