Sub-window rendering becomes corrupted when enabling and disabling OCIO: https://dl.dropboxusercontent.com/u/21559589/krita-bug/OCIO-multiview-bug.png In addition, krita will take up 100% CPU usage when in this state. "fullscreening" one of the sub-windows fixes the issue and makes the CPU load go away, but once one goes back to tiled view, it happens again. Confirmed to exist with a freshly compiled version from the calligra/2.9 branch. Reproducible: Always Steps to Reproduce: This bug is a bit spurious and laborious to reproduce, but it does seem to happen reliably. I'm not sure what exactly triggers it (whether it's OCIO or the tiling) but this procedure seems to reproduce it 100% of the time for me, even if sometimes it requires a bit of additional messing around with the OCIO docker and resizing/moving subwindows until it happens: 1. Create two new documents 2. Window > Tile 3. Enable OCIO, set view to sRGB, disable OCIO 4. Minimize krita, unminimize krita 5. move the subwindows around 6. rendering corruption occurs Some of these steps might not be necessary/matter, but this does reproduce it for me reliably. The bug does not seem to reproduce with OpenGL disabled.
Isn't this pretty close to the other tiled-window bug you reported some time ago? I'm still pretty confident that it's driver issue...
Which bug is that? I can test if it still occurs with OpenGL disabled.
https://bugs.kde.org/show_bug.cgi?id=347620 I think. Here is the list of all bugs you reported :-) https://bugs.kde.org/buglist.cgi?bug_status=UNCONFIRMED&bug_status=CONFIRMED&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=RESOLVED&bug_status=NEEDSINFO&bug_status=VERIFIED&bug_status=CLOSED&email1=jwringstad%40gmail.com&emailreporter1=1&emailtype1=substring&list_id=1286612&product=krita&query_format=advanced
Hm, it's not obvious to me whether the two bugs are related, the multi-window multi-view bug just causes a bit of laggyness (and some input errors, so that definitely can't be related to the driver) while the other bug causes corruption on the UI parts (view decoration) itself. I might have some time to investigate this weekend, if there are any steps you know that could help narrow this issue down.
Argh... And the dropbox link has expired of course. But I still cannot reproduce anything like this...
I'm sorry, but I need info on how to reproduce this reliably. Also -- is show contents when moving subwindows enabled?
