My app works fine in the main user of my Mac. However when I open it in another user on the same mac, I get flicker (flickering square patterns) inside any container controls that get moved or scrolled. The size/shape of the squares doesn’t seem to correspond to any underlying controls or containers that I’m aware of.
The problem didn’t occur previously but I am now noticing it in OSX10.11.5 with Xojo 2016 r1.1.
I ran into the same issue today and I remembered this thread. Just wanted to report.
Maybe others could try to create a test user and run a Xojo App that has a repainting Canvas?
I know my App would flicker on Windows because of some stacked canvasses but the flicker is really bad. Never saw it on OS X before. It’s like things are being repainted really slow or something.
Compared to the ‘main’ user, the black (shadow?) is also showing way more often before the Window displays. But the main issue is that things are flickering like crazy. White blocks everywhere when repainting the canvas.
I’m on El Capitan (10.11.5) with 2016R2.
It doesn’t matter if the same App is running on both users at the same time or not.
Even if I create a new Admin user and I logout from the ‘main’ user, it’s still flickering.
I have no idea if this happened in the past or not because I never tried it before.
Good example.
It flickers although I have an App that flickers a lot more (but I think it’s because I use timers to update things while downloading).
Did you file a bug report with this example?
