Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Fedora Linux (Wayland Gnome 45.3)
Graphics card: AMD
Blender Version
Broken: really broken in 3.6.5 (e2b5e831) until 4.0.2 (current version), some visual bugs since at least 3.3.0
Something changed in 3.6.5 (ed38ca98g), the bug only happens when maximizing there, not when un-maximizing. Although when the window is grabbed from a maximized state it is the wrong size there too, but it resizes correctly as soon as it refreshes.
Worked: ?
Short description of error
Sometimes a Blender window is the wrong size
Exact steps for others to reproduce the error
Un-maximize and maximize a Blender window a few times.
This happens without any fractional scaling on GNOME 45.3, so it might not be related to #109194.
Window snapping triggers the bug very reliably. The video is not edited.
@max-mustermann could you please test with a recent daily build of 4.1?
There have been multiple fixes to LIBDECOR's window size logic since 3.6, so the issue reported here may be resolved.
Related fixes for reference:
004420af8ff845a3992c145531511139f378da37ba33dba2b6dcaeed7522I have tested a daily build of 4.1 and 4.2 and most bugs shown in my window snapping video still persist in both.
@max-mustermann for this report to be useful we need to know which bugs remain.
They mostly involve a second window.
1:
Have both windows snapped to a side.
Grab the second window.
The second window will look like this sometimes until it refreshes.
When maximizing before it refreshes, it looks like this:
2:
Have both windows snapped to a side.
Grab a window to "unsnap" it.
The other window will shrink in size sometimes.
This is permanent until the other window is resized.
Edit: Found a more consistent way to trigger Bug 2:
Open Blender (and click to get rid of the splash screen).
Snap the window to a side.
Press F11 to open the Blender Render window.
Move the Blender Render window using SUPER+LMB to snap the Blender Render window to the other side.
Unsnap the main window.
The Blender Render window will shrink in size too.
And I get a Gnome notification that Blender crashed with a segfault but I don't notice anything crashing and there is no output in the console about a crash.
Maybe this is related, but repeatedly opening and closing the Blender Render window (F11, then closing the window with X) gave me this error in the console:
After that error was triggered, version 4.0.2 would not be able to open a new Blender Render window, but other windows like Blender Preferences would still open.
In the most recent 4.2 daily however, Blender becomes completely unresponsive to all inputs as soon as the bug is triggered. So this is a regression within the bug? Do I open a new report for this?
Repeatedly toggling window fullscreen with Window -> Toggle Window Fullscreen makes the window extend beyond the screen on the bottom after the second cycle.
Edit: Seems to be fixed in the recent daylies.
Maybe fixed by
e078112a53?Sadly it still happens in the recent daily, but I can't trigger the following bug in the recent daily anymore:
I found a more consistent way to trigger Bug 2. I updated the comment about it.
Blender 4.1.1:
When starting out with a maximized window and then unmaximizing it, Blender becomes unresponsive to all inputs until the window focus has been switched away and back to Blender again. This only happens the first time after Blender has been started.
It seems related to window sizes so I'm putting it here.
