GPU access conflicts after a Bitdefender update usually trace back to the hypervisor protection or advanced threat defense module flagging the GPU process injection that certain applications use for hardware acceleration. Vivaldi specifically uses Chromium's GPU process architecture, which can trigger false positives in aggressive behavioral protection settings.

A temporary workaround worth trying is adding both Vivaldi and Termius to the Bitdefender exclusions list under Protection, Advanced Threat Defense, and Manage Exceptions. Add the full application executable path rather than just the folder.

If the exclusion does not resolve it, check whether the Bitdefender update changed your ransomware remediation settings, as that module sometimes interferes with applications that write to GPU memory buffers during rendering. Rolling back to the previous definition's version temporarily while Bitdefender investigates can confirm whether the update is the specific trigger.
