Description John 2017-05-12 10:26:02 UTC
Created attachment 105468 [details] Display when zoomed in and out Setting more than one fisheye assist and zooming in to the image where the canvas is larger than the view window causes the canvas to go completely black. Zooming out returns the canvas to normal. Removing any extra fisheyes restores normal behavior. Fisheye with other ruler or vanishing points does not create this effect.

Does this also happen if you disable opengl? And if so, what display chip do you have, and what is the driver version?

(In reply to Boudewijn Rempt from comment #1) > Does this also happen if you disable opengl? And if so, what display chip do > you have, and what is the driver version? Black screen does not occur while Opengl is active. Chipset: AMD Radeon R9 DriverL\: 22.214.171.124

Do you mean "inactive". I seem to remember having heard about this problem with AMD graphics cards before, though. There's something buggy in the driver, but since we don't have access to a broken driver/hardware combination, it's impossible for us to find a workaround.

Yes, I meant to say inactive. :P I certainly was not expecting an instant fix. If there's any additional data needed, let me know. I'll experiment with a few other drivers.

Hi John, Can you check with the latest version of Krita and enable the Angle renderer? That uses Direct3d, so that might work around the bugs in the AMD opengl driver.
