Description David 2015-12-17 12:01:49 UTC
While using the Intous 5 wacom tablet, after scrolling with the wacom wheel to zoom in / out the canvas lags. It doesn't render the canvas' zoomed in state until I either click something else on the desktop, or go over it with the mouse cursor. 

Reproducible: Always

Steps to Reproduce:
1.Open new canvas with any size. 
2.Use wacom tablet wheel to zoom in/out

Actual Results:  
Unloaded/rendered canvas.

Expected Results:  
 Load/render the canvas as you're zooming in/out.

Computer Spec:
i7 4790k
16g Ram
SSD 120g
HD 1T
GTX 760 Nvidia 


This problem doesn't happen with other graphic applications (paint tool sai, photoshop)

Hi David,

This problem does not happen generally, as far as I know, so it must be something peculiar to your system. * Does it also happen if you zoom in/out with the mouse scrollwheel or the keyboard zoom shortcuts? 
* Do you have opengl enabled (and if so, is your driver the latest version?) 
* Does it also happen for you if you switch opengl on/off?

When I use the mouse alone it doesn't happen as bad. You can notice some
render delay but it's hardly noticeable. It happens mainly with my wacom.
Open GL is enabled.  Version 4.5. It still happens when I switch opengl
on/off.

Hm, if it also happens when opengl is switched off, it cannot be a display driver issue. But I still haven't seen anything like this... You don't have transform masks or something like that in your test images?

Apparently it's a windows 10 thing. I reverted back to windows 7 and it
works perfectly.

Okay, then I'll close the bug. There isn't much we can do about Windows' weirdnesses.
