vanyossi <ghe...@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REOPENED |CONFIRMED --- Comment #27 from vanyossi <ghe...@gmail.com> --- The canvas is not correctly updated when texture buffer is active. This happens at least from this version up to 5.2.0 beta and master. The issue before going with 16 buffers was a completely transparent (with small images) or semi transparent images after a canvas operation and pan/move/paint with bigger ones as shown in bug 398689. With the current code an the 16 buffers only some of them fail to update sometimes, leaving. a portion of the image without redraw and showing the checkerboard as shown by bugs 459458, 452655 and 473806. If the image is small enough it can make the entire canvas become transparent. My current testings are using M! with master (e0fa60d68f) and 5.2.0beta This is a display error, no data is lost and hiding/showing the a layer makes the image redraw. I'll close all duplicates and use this bug as is the first one to mention a problem with texture buffer with macOS (Nvidia and M1-2). -- You are receiving this mail because: You are watching all bug changes.
