The Xibo Player freezes after several hours connected to a Sharp NEC C750Q from [KAMRUI Essenx E2 Mini PC, 16GB RAM 512GB SSD Mini Computers,12th Alder Lake N97](https://www.amazon.com/KAMRUI-GK3-2-5-inch-Ethernet-Business/dp/B0D5LGMYY7/ref=sr_1_3?crid=315MBBDX18R74&dib=eyJ2IjoiMSJ9.tXQwrqGeVtJoEk7VGFH6jbrxkgq7TxuUmU3n5AF8V3VDRr-oB6Aq_JYgm9vDeVavJjmdP1GKP-ze2Jbm3ZjhQCd3OA-rzYjjoK9p6HLdaHRLmEChLSPGaYsDBaXhS7M9Cob8Ny9AJ_395I0zJ5TVOuKequXIYTIMdZ6IUiL1HTrdNoMwAbuhbQPr2OjOFbcETWKW_z25RgXBh75qK3WW9PxXjD2ucOwihhpdMqWqgbO0rF0YRIfjd0_yArjLwcRi0Kv27j40KZNlYahnlzpY7ZmVeAi8pdP0CPwQ9sOWySE.4ZC_zBq_tWMfeP9sSjo6_IKJyXSo0J0UNqhX2Vqu_F0&dib_tag=se&keywords=mini%252Bpc%252Buhd&qid=1755526688&s=electronics&sprefix=mini%252Bpc%252Buhd%252Celectronics%252C92&sr=1-3&th=1) running Windows 11 Enterprise 64 Bit 24H2.

Looks like this is caused by a memory leak, and I cannot provide a long term fix at the moment. Still, I just want to thank you for the way you described the issue, it was exemplary.
As a temporary workaround, you can increase the virtual memory in Windows, which should delay the impact of the leak.

I increased the virtual memory as you recommended. I will wait until Monday to see if that resolves the issue. Thank you for the suggestion.

Increasing the virtual memory did not resolve the issue. However, trying different resolutions seems to fix the issue. I set the display resolution to 3840 x 2160 with a scale of 300% for the NEC M551 and C750Q models. Schweminska, thank you for your help.
