Since updating to version 11.0, I’ve noticed a major issue with window management:

• Erratic Window Behavior: When moving a window to another monitor (method [1]) or another location on the same monitor (method [2]), the window rapidly "flashes" between its original and target locations for 1-3 seconds.


• Inconsistent Results: After the flashing, the window may not stay in the intended location and sometimes reverts back.

Method 1 - use keyboard shortcut to trigger functions like "Move Window to Previous/Next Monitor and Size Proportionally".

Method 2 - use keyboard shortcut to trigger functions like "Size and Move Window to Left/Right Side of Monitor".

----

To replicate the flashing issue, for a multi-monitor setup, quickly repeating the keyboard shortcut in Method 1 will reliably trigger the behavior. Similarly, in Method 2, the issue can be reproduced by using shortcuts to move the window to different portions of the same monitor in the following sequence within 3 seconds: left → right → left, followed by a brief pause.

[Update 1] Attached is a screen recording demonstrating an issue with moving a window across two monitors set up in portrait mode and positioned side by side. As shown in the recording, when I move the window counter-clockwise, it begins to flash rapidly.

Thank you for confirming.

When using the "Move Window to Previous/Next Monitor and Size Proportionally" function to move windows between monitors, I've noticed another issue: Sometimes when using these keyboard shortcuts, there's roughly a 10% chance that the window becomes completely invisible after switching displays. Based on my observations, this seems to happen more frequently with Chrome windows compared to Firefox, though I'm not entirely certain about this pattern.

Good to know! Will upgrade to v11.0.3, and keep log on. Thank you!

I’d like to report that the flashing bug has been resolved in Version 11.0.5. However, I’ve noticed that the "Move Window to Previous/Next Monitor and Size Proportionally" function is now behaving differently. Specifically, when the resolution or layout of the target monitor differs from the source monitor, the resizing process takes noticeably longer and exhibits significant visual glitches. This issue might be related to my dual-GPU setup, which involves a total of seven monitors.

For now, using the simpler "Move Window to Previous/Next Monitor" function works well. It moves the window to the target monitor instantly without any delays or glitches.

For demonstration purposes, I’m attaching a screen-recording showing the results of moving the DisplayFusion Settings window across all monitors. The test includes three scenarios: first using the plain "Move Window to Previous/Next Monitor" function, then using the "Move Window to Previous/Next Monitor and Size Proportionally" function, and finally switching back to the plain function. All function calls were triggered by the same hotkey, which I reassigned between test batches.

Starting at 00:38, one can observe visual glitches during the proportional resizing process. The Settings window repeatedly resizes back and forth when moved to monitor 2. At 01:22, after switching back to the plain function, the window moves seamlessly between monitors without the additional resizing overhead.
