another app visible thru transparent canvas
Transparency on Linux Direct3D |
||
It could be that it was introduced when we added support for HDR. Maybe we should just remove the direct opengl mode on windows... *** Bug 405679 has been marked as a duplicate of this bug. *** Created attachment 118988 [details]
Transparency on Linux
It happens for me on Linux (KDE) too - I added a screenshot.
Same behavior when I launch Krita with optirun.
I found that disabling the compositor with Shift+Alt+F12 fixes it.

Here is the info for the integrated Intel GPU on the same laptop.
Again, the see-through issue remains.

I can confirm the bug on Linux... Git commit e1d56f30d513b7f08124ba8eea300b76ce4b3e7e by Dmitry Kazakov. Committed on 26/03/2019 at 10:26. Pushed by dkazakov into branch 'master'. Make sure Krita doesn't request alpha-enabled texture buffers glBlendFunc doesn't support correct alpha blending (alpha channel value should be calculated separately), so we must ensure that the calculated alpha value is just dropped entirely.

OpenGL works OK but Direct3D don't. See attachment. Maybe these are related? |
Created attachment 118456 [details] another app visible thru transparent canvas SUMMARY Window of another apps behind Krita become visible partially when opacity of layer is less than 100%. This bug only happen when OpenGL is active. Workaround is to use Direct3D 11 via Angle. STEPS TO REPRODUCE 1. Configure Krita to use OpenGL. Restart Krita. 2. File New 3. Change opacity of Background layer 4. Start some application and switch to Krita so it overlap started app. 5. video appear in canvas with reduced opacity. See attachment. I noticed this bug since krita-nightly-x64-v4.2.0-prealpha-308-g7d4289d8b0.zip but I'm not sure when it was introduced. Current Git 7d4289d. Tested on two Windows 10 computers with nvidia760 and nvidia1070 - both with generic nvidia drivers.
