Can confirm that this started happening within the last month or so. X11 and Wayland are affected. Git commit 4912c7cfa2e54c2f5ad491f868aaae43135ca172 by Vlad Zahorodnii. Committed on 11/08/2021 at 16:43. Pushed by vladz into branch 'master'. scenes/opengl: Calculate item transforms differently Currently, a vertex coordinate is transformed first, then mapped to the global screen coordinates. This causes a problem if a transform is applied to the top-most item and child items are not at (0, 0). For example, scaled windows may have popping out sub-surfaces, etc. With this change, the item transforms will be computed differently. For example, if the parent item is transformed, a child's transform will look as follows [Parent's translation][Parent's transform][Child's translation] instead of [Parent's translation][Child's translation][Parent's transform] In the future, I'd like to get rid of the Item::setTransform() call in OpenGLWindow::performPaint() and have either AnimationEffect or libkwineffects call Item::setTransform().

( it used to look like the window was divided into 4 parts all growing ) |
Created attachment 140284 [details] Screenshot of the bug Windows appear detached from their titlebars in Present Windows and Desktop Grid. Plus they have a shadow which seems to be not in the right place. Screenshot attached.
