Canvas freezing after unified transform
Environment/Versions
- GIMP version: 2.99.14 and earlier betas. Not yet observed in 2.10
- Package: Gimp project beta flatpak
- Operating System: Linux
Description of the bug
During a unified transform operation, the canvas freezes and does not refresh. The operation can be completed as can other operations, but the canvas does not update any more. The progress bar will reach full completion and not disappear, and the canvas will not repaint, but all menus and controls work normally indicating that the transform operation has completed.
Reproduction
Is the bug reproducible? Always and observed on two different computers.
Reproduction steps: It will take me some time to develop a test case so more info to come. Attached is a screenshot showing incomplete repainting of the screen after an attempt to force the screen to repaint by changing the size of the application window. On numerous occasions that computer has been left running for many hours attempting to get a full repaint which has not occurred. Whilst the screenshot would appear to show the application has frozen, all the menus and controls can be operated normally, and moving the mouse over unpainted areas of the screen will cause them to be repainted as normal. Part of the testing is to roll back one of the computers to 2.99.12 and check to ensure the issue really is new on 2.99.14 with the same project file.
