Bad rendering on iPad only

[jmburnod]

Hi All,
I get a strange rendering with an iOS app. All works well on IDE and standalone for OSX (LC 9.01, iOS 11.4)
• Some objects seem absent (not the same all the time) but i can show some of them when i click them with my finger
• Some btns seems greater than their original size
II tested with acceleratedrendering or not, it seems that is better when it is false
Thanks in advance for your advices
Best regards
Jean-Marc

I see this in some older stacks. A temporary fix sometimes works to force a card redraw:

Code: Select all

set the backcolor of this cd to the effective backcolor of this cd

LC 9.5 has some redraw issues when acceleratedRendering is true.

Thanks Jacqueline,
I tried:

Code: Select all

set the backcolor of this cd to the effective backcolor of this cd

at opencard
Some problems remain but i can call one message that didn't work before.

I try to track errors with

Code: Select all

on errordialog pExecutionError
	answer "error on line:" && item 2 of line 1 of pExecutionError
ënd errordialog

and i sometime get an error on line 0
I have to understand this as an error at preopencard ?

I'm never sure what error at line 0 is. Most of the time I think it means the compiler doesn't know either. It only knows the script wouldn't execute.

Maybe it's something in one of the LC libraries, but it's hard to tell.

OK I will track with answer message to know last message executed

I've compiled for iOS 13 (LC 9.5 xCode 10.1,) display problems seems fixed with LC 9.5.
