Subject: 1.6.5: XnView buggy/blinking after playing video in fullscreen

XnView: MP 1.6.5 - 64 bit
OS: Windows 11 - 64bit

When start playing video in fullscreen from browser view, XnView blinking several times when going back to browser. After that, every time I switch from Browser <> Fullscreen always blinking, sometimes not rendering picture. This bug does not happen in viewer mode, switching from Browser <> Viewer is normal.

To reproduce:
1. Open XnViewMP in Browser mode.
2. Click a video, switch to Fullscreen mode.
3. Going back to Browser mode.
4. Switching Browser <> Fullscreen pictures/videos always blinking at this point.

Expected behaviour: Switching Browser <> Fullscreen video should not blinking
