windows - Firemonkey Scrambles graphics on laptop -
i have application plots quarter degree blocks on map using timage stacked on each other. add records drawing them on separate layer.
the problem have firemonkey (or windows) scrambles graphics, on computers, , think affected computers laptops. see following links screenshots:
the correct image should this:
on laptops scrambling may take 3 repaints of layers, (on same code) happens after 1 or 2 times. while inconsistent in how many repaints takes, guaranteed happen after no more 3 paints.
so have come conclusion must graphics driver issue. have nvidia geforce 950m on laptop (asus nj551 windows 10), if understand code correctly using windows direct2d acceleration nvidia drivers shouldn't affect things?
i set following flag default: globalusedx10software := true; //use directx generate graphics, not seem make difference still scrambles when set false.
i prefer windows acceleration users may not have graphics card installed. friend using hp laptop (not sure of model running windows 8) not experience issue, yet friend brand new hp laptop (low spec windows 10) experiencing issue.
can please out here? out of ideas, , i'm not sure google. windows 10, graphics driver, etc? there way can force laptop use graphics card testing? while not other users without proper graphics cards, may isolate issue.
any advice appreciated!
from edn forum, got number of other graphics related global variables set. 1 sorted out issue is: globalusedxsoftware := true;
it makes sense, issue started happening after moving xe8 xe5, , globalusedx10software flag deprecated
