Re: Blue/Purple Screen on New Android

Do you mean the main menu displays correctly during 1 second, then have the bug during 1 second, then this sequence repeats ? It's a useful information for me.

It's possible. But it happens only on some devices, and the options "disable hw overlays" and "force 4x msaa" fix the problem. I don't have skills in SDL but I think these options are not related to color space. Because this bug happens on powerful devices, it seems that slowing down the GPU helps to fix the problem.louis94 wrote:Maybe the wrong color space is somehow selected at startup?
Code: Select all
display_splash('userdata/presplash.png', (255, 255, 255))
+ time.sleep(5)
os.chdir(get_internal_storage() + '/package')
+ display_splash('userdata/presplash.png', (255, 255, 255),300,0) # move to the right
+ time.sleep(2)
I'll try this, but I don't know when I've time to do this.louis94 wrote:I'd try to reproduce with some basic SDL demos to rule out an upstream issue first.
